I googled IPv6 and WP7 and found that mango is suppose to offer this to WP7.
My Nokia Lumia 800 however is blissfully ignorant when it comes to IPv6, it simply doesn't get an address and is therefore unable to connect to any IPv6 host.
Now I don't have any other handsets, so I cannot determine if this is a Nokia special, or that Mango doesn't offer any IPv6 support, contrary to the articles that claim it does offer IPv6 support.
Can anyone chime in here ?
Does your Lumia receive an IPv6 assigned by your carrier? I guess if your carrier dosn't assign IPv6 adresses you can do nothing about this...
I have IPv6 configured on my local network and I can confirm that Lumia actually gets an IPv6 address (public, routable one, not only link-local) and I can also ping it over IPv6.
It doesn't, however, seem to open any IPv6 web pages and all the pages with both v4 and v6 fallback to v4.
Hmm, how did you find out it got an IPv6 address ? Whireshark ?
As far as I know, there is no way of checking on the device itself, in any case, sites like test-ipv6 com report that the Lumia doesn't have any IPv6 address.
It is strange, as I have a dhcpv6 server for statefull configuration (mainly pc's) and I also have two IPv6 routers that advertise RA's to devices. My Nokia N82 and E72 and the IPAD2 all get global addresses and are happily surfing to IPv6 sites.
I presume you are on Mango or 7740 ?
I've first checked ARP table on my computer, found IPv4 of my phone and matched its MAC with a list of IPv6 neighbors (netsh -> interface ipv6 -> show neighbors).
And yes, it is Mango.

Sorry should have mentioned, my home network is fully IPv6 enabled for about two years now. I run one native IPv6 connection, where I get a :/48 prefix. My main line (in speed) is a tunnel connection over Ipv4 with a different :/48 prefix from the tunnelbroker.
The setup is such, that my Servers all get a fixed IPv6 address in the first available :/64 and are routed over the tunnel. My Windows PC's get routed over the same tunnel using a DHCPv6 server, all other devices either go over one or the other, depending on which RA (route advertisement) gets to them first, as both IPv6 routers also advertise their routes (pc's are setup not to listen to ra's in any case).
This works fine for my two Symbian powered Nokia's, as well as for the IPAD2, they only device in my house who seems to be unaware of IPv6 is the Lumia.

Are there websites that you use that are only accessible through IPv6?
http://test-ipv6.com tells me that I don't have access to IPv6 from work.
Your IPv4 address on the public Internet appears to be xxx.xxx.xxx.xxx
No IPv6 address detected [more info]
You appear to be able to browse the IPv4 Internet only. You will not be able to reach IPv6-only sites.
Your DNS server (possibly run by your ISP) appears to have IPv6 Internet access
My iPhone through 3G on AT&T gives the same result, expect the last one, which says:
Your DNS server (possibly run by your ISP) appears to have no access to the IPv6 Internet, or is not configured to use it. This may in the future restrict your ability to reach IPv6-only sites.
This is not even using Wi-Fi. So, major carriers aren't even supporting IPv6 browsing yet. It's not iPhone specific. Just being on AT&T 3G in Minnesota means no IPv6.
I'd like to know of even 1 real site that this prevents you from accessing.

Just read your post above.
What problem are you experiencing on your network by the device not having an IPv6 address?
Why not also support IPv4 in your internal network?
It's pretty unlikely that you would need that many addresses internally.
Yes, IPv6 on 3G (cellular network in general) support is really limited and it is much harder for both operators and mobile phones to support it.
It would be, however, about time, that WP starts supporting IPv6 over wifi.

I do support IPv4 on my internal network as well, that is not the point. It is 2012, all my devices run dual stack, and I think it is time that a Nokia released in November 2011 should also be able to handle dual stack and connect using either IPv4 or IPv6, I mean come on, even a Nokia N82 which is over three years old can do it !
And yes, if I go with a pc, or the ipad or the N82 to that Ipv6 test site, they all report a global IPv6 address and pass with flying colors, the Lumia only has a IPv4 address.
Oh and to make myself clear, (if it isn't obvious from previous posts) I am not talking about 3g, I am talking about my home network over wifi.

I understood that you were talking about your local network with WiFi. I only mentioned the 3G, to show that the carriers are not yet even giving access to IPv6 only Internet sites.
Is the reason you need this to get to IPv6 only internet sites from home?
Or do you restrict access to some machines on your network to machines with IPv6 addresses for the security advantages?
Or is the reason strictly because the number of IP address under IPv4 is running out and at some point new sites will be forced into being IPv6 only? At that point the phone will not be able to access the new sites.
I don't see a reason for Nokia not supporting IPv6. It's been around for a long time. We've know it was needed for a long time.
The only thing I can think is that most phones are only used for about 2 years and you aren't going to see alot, if any, major sites switching to IPv6 only in that period of time. Realistically all major sites will support IPv4 for at least 5 years or longer.
Yes, Nokia should support it. But, phones not supporting it today are not going to cause typical users any problems.

All you say is true, yes there is no problem now, the phone supports IPv4 just fine, however, since it is 2012, and since IPv6 is around for > 10 years, I am utterly disappointed by either WP or Nokia not fully supporting IPv6, and this should really be rectified asap,regardless of all the things you said. Not to mention the fact that in Asia things are quickly going to IPv6, simply because they did already run out of IPv4 addresses.
The sooner we get rid of IPv4 the better, the stack has run it course and is redundant.

Sorry, I made a big mistake by making false assumptions. It appears that the IPv6 enabled Nokia was actually Nokia E52 (I've only checked MAC vendor and forgot about the other phone having wireless enabled).
It seems Lumia doesn't get IPv6 after all.

At work the wireless network has global IPv6 connectivity and the webservers in another network are acessible via IPv4 or IPv6, the web access suceeds, it's really fast, and the IPv6 enabled sites are accessed via IPv6 automatically.
At home, my local network only have IPv4 connectivity (Cheap Linksys router/ISP limitation) and when I try to access my work sites or any other IPv6 acessible site, the PDA spends 30-60 seconds trying to access the site via IPv6 and then falls back to IPv4 and shows the site ...
This is really annoying for "browser" navigation ...
(I'v captured the packets sent by the PDA if anyone want to deep analyse them ...)
Does anyone know any solution for this problem ?
Thanks.
Just updated my HD7 to the update with internet sharing. After this, I can confirm that every time I reboot my phone, I get a new mac address. Which prevents me from connecting to my MAC-address-filtered wifi. I've done it 6 times and gotten 6 unique MAC addresses.
Does this happen to anyone else's phone? HD7 specific? or all phones with internet sharing? My internet sharing is turned off.
That's strange, I've never heard of a device with a dynamic MAC address before. Does your phone have one printed under the battery?
Nope, just IMEI, SN and PN. No MAC address.
This must be related in internet sharing somehow.

I can confirm this on my HD7.
MAC changes on every reboot.
I confirm too,i have the issue of mac adress changing every reboot
& my wifi is not visible since the update,My wifi is N and i can only see wifi G near me but not mine
hi
for me too : mac adress change after shutdown.
for time don't shutdown the phone to have same mac adress with my internet box.
htc support tell me that they will answer on monday.
but i think it's a big problem with this update...
Ben
That's a bit strange. Normally you can't change MAC's for yourself, only spoofing is possible. If WP is really changing the MAC adress with every reboot, WP needs a valid MAC adress block licensed from IEEE, otherwise it would be a violation against IEEE.
I thought mac address we're never aloud to change!?
Lol that's illegal as all hell, a dynamic mac address
Gotta be a glitch in the firmware surely? No way that's allowed. Your definitely sure it's not a dynamic IP address you're seeing?
Sent from my SGH-i917 using Board Express
ive also asked this question a couple of days ago right after applying the htc internet sharing update. and ive posted my question here (entry #38) and people provided good answers about it. hope this helps
Yes, mine also changes it's only when i read this thread and test my hd7 and i notice the changes.But I S is a breeze.
The issue is that some people assign static IPs to devices on their home networks, and this is done in most routers via MAC address coupling (MAC a always gets IP z and so forth). That way you can simply block all devices you and people in the residence do not own. I do it on all my machines for development reasons, cause I like knowing I can always use x IP address to get at a certain machine even if I turn it off or it's down for a while for repairs. The IP never changes as long as I continue to use that specific network card in the computer.
I don't know why they would do that. Perhaps for security reasons?
I have the same problem - cannot connect to my University WiFi network as the MAC address keeps on changing....
This is crazy!
They better get on that quick! They could get in a lot of **** for that
putting aside the weird WP7 behaviour for the moment...
MAC filtering is useless as a security measure. It's trivially spoofable by anyone who actually wants to attack your network, and causes a pain in the arse for yourself. do yourself a favour and disable it already. the only thing it might be good for is router-side internet access control of your technically challenged 8 year old who doesn't know how to use google.
just use a strong password i.e. 20+ characters alpha (upper & lower) + numeric + special characters, and proper wireless security (WPA-2 AES, or at least WPA AES) and you'll be just fine.
Confirming
That update was a bag full of $$$$ !Luckly I was able to restore through Zune,but my Bootloader (SPL) was also updated to 5.01 and no way of going back!
With regards to the missing WiFi network - make sure it's not using Channel 13. The new update seems to disable the use of Channel 13 for some reason.
There is also another issue with the changing MAC's - I believe that some "public" WiFi networks such as the cloud use the MAC to remember your device and allow it to connect...

Mac filtering is not useless as a security measure. It's not used by itself. It's used in conjunction with other methods, the same way businesses also hide their wireless network's SSID.
I'm not filtering on an Open Connection. That would be retarded.

im not sure though but im guessing so does other apps with secured log in parameters. i do have the bank of america app. right after i did the update, and after inluding the new mac to my networks allowed list of mac addresses, the boa app again posted a message saying that the device where im accessing boa has not been used previously to access the account. so im guessing that it saves all the mac addresses of devices that accessed a boa account.
Greetings...I'm trying to determine the MAC address of my HTC TP2's 3G radio. I am setting up a firewall rule to only alow a specific MAC address to pass for specific services. Any ideas as to how to determine the MAC address of the internal radio?

MAC of the 3g radio...? Certainly you mean the wlan radio.
When I enable wifi in WinMo, there's an "advanced" button at the bottom. Then choose wi-fi info, IP and MAC.

Not the WiFi radio...the 3g radio as I need access outside my network through a UTM. I guess the first question should have been, is there a MAC associated with the 3g radio?

Odd.
I'd guess there is, but I've never heard of anyone caring about it lol. IP probably wouldn't work so well either, what about hostname or smth else?
What if you lose your phone?
I'll see what I can dig up.
Edit - wait... if your packets are going thru a layer-3 router (which undoubtedly they are at some point) the MAC will be lost. So this won't work at all, even if you did find the MAC of your phone.
Response...
I couldn't find anything through searches....The IP would be of a dynamic nature so I couldn't use it however the thought about a host name is an idea. I'll have to inspect the packets to determine if a host name is present. On my inital inspection I captured a MAC however that MAC seems to be dynamic and did change a few times using one of two MAC'S thoughout the capture. Also...during the capture I captured IPv6 MAC's....not IPv4. I'm just wondering if the CDMA network assigns a dynamic MAC instead of using a hardware based MAC? I would find this highly unlikely however it could be a possibility.

Please read my edit about layer-3 routers. I'm having this same problem at work, in relation to sniffing VoIP RTP streams passively. When crossing a layer-3 router/switch, the MAC is lost in transit.
Response...
I believe I finally nailed down the actual MAC address. My packet monitor was set for the monitoring a different port on the switch.....should have been set for X1 instead of X0. I'll make the changes to the firewall and all should be good. This exercise is for a handheld utilizing a SIP client tied into my VoIP server....I only allow specific SIP clients to access my VoIP server....helps prevent hacking and unauthorized phone use.
Thanks,
Chris
Response...
I'll report back my findings after I make the configuration changes.....I am assuming this will work as I already have this in place for all SIP providers currently in use.
Thanks,
Chris
Findings....
Ok...one small detail I forgot.....is that MAC addresses change with each hop. With that being said.....the only way to "filter" incoming packets is to filter by IP address. I currently filter all SIP related protocols by carrier/provider IP address. Now this creates an issue due to the fact handhelds outside of the network will have dynamic IP's assigned by the cellular carrier. I'll have to continue to research this....I believe the only work around might be a VPN tunnel originating from the handheld into the network.

You mentioned loosing the MAC address across a layer 3 router....the MAC address is lost across any router regardless of it's layer capability thus I will implement a different solution.

What router operates only at the layer-2 level? lol.
So no to long ago I decided I would check the my phone's ip address and came across some questionable stuff. Here's my question:
1) How is it that my phone's ip address can change from being registered to tmobil on a 100.x.x.x address to sporadically being registered on DoD 30.x.x.x address?
2) How can it still happen even after I installed android firewall?
Conditions are always the same. I don't download any shady anything's. I pay for my rhapsody account and that's as far as my file sharing goes. I never have my WiFi enabled.
Any ideas or let me know what info you'd need to better access the situation. Thanks.
Without knowing what the allocated ip address really was, there it's really no way of knowing who the current owner of the block is, many blocks are relocated and may no longer be with who they used to be with, especially ipv4 blocks.
Not sure what android firewall would have to due with what the remote ip you are being allocated to with your dhcp network connection.
You should have no real control over what your network connection is given when you connect, other than possible controlling ipv6 vs ipv4.

So does this help? the firewall lets me know that even though I have set it up to refuse the block of addresses in which in resides, they're still connection to my phone.
Not sure I'm understanding you anyway. You telling me they temporarily relocate my up because they re no longer with.... yet after a few minutes , sometimes hours, I'm right back to the same ip?
What he was saying I believe is that the IPv4 allocations have been changing do to the available IP address blocks running thin. Companies were encouraged to give up IP blocks that they weren't actually using. In simple terms, a company might have originally owned a block of 100,000 IPs but never actually used more than 50,000. So they gave back a block of 50,000 so another company(s) could use them instead.
I don't believe the IP address' are static on a carrier. I'm not sure but each time you connect to the carrier network (no signal or airplane mode) you could be giving a fresh IP address. Also that is certainly the case if you are on a WiFi network. Unless you phone was set up as a static connection, you would likely receive a new lease on an IP address.

Exactly. Internal allocate IP's are normally Natt'd and not actuall the IP you show up on the Internet as.
When you connect to your provider for Network (not using WiFi), the provider (most likely T-Mobile) will allocate an IP to you via DHCP. That IP is what your phone uses to talk to the provider. It most likely is NOT what you look like when you hit the Internet though, that will most likely be a different IP because TMobile is most likely not providing you with an Internet routable IP.
So, right now, I turned off WiFi and I got the IP 100.143.28.84. When my phone touches the Internet though, it shows up as 206.29.182.169.
So at that point in time, my phone is using 100.143.28.84 to get to T-Mobile's network and the Internet sees my phone as 206.29.182.169. the outside IP is in TMobiles published block. And why the internal IP is also, it really doesn't matter what it is because that is not what your phone looks like when it gets to the Internet.
It is possible in your area there are different networks available internally that are given to you when you connect depending on where you physically are and what towers you are closest to. At some times you get the 100.x network and you might even get the same IP as before because of a lease of that IP to your device, but then you move to a slightly different area which is handing out 30.x addresses. All perfectly normal. and the internal IP's really don't matter much.
You can use a search of Whats My IP to see what the Internet thinks your IP is when you get there.
With some providers (Verizon for example) if you are using ipv6, you will always get a non-routable IP, meaning that if you figure out your Internet IP, an outside connection may not get back to you unless your device initiated the connection, but if you use ipv4, they gave you a temp IP that would end up with a routable IP back. You could then use that to connect to your phone using something like VNC or other service. Now days, that is much more likely not the case unless you are paying for that special IP service. I don't know if Tmobile offers that type of service, but Verizon did at least a year or two ago.
In anycase, you firewall shouldn't matter unless you don't want to access your providers network.
In lamens terms I think he's talking about an internel subnet mask

That was a very interesting article. If the author's theory is correct, T-mobile was playing some cute and dangerous IP games in 2010.
I'm trying to run some network services (servers listening for incoming connections) on my LG G3 phone. Its rooted, though all the services that I want to run do not require root to function (they use unpriviliged ports).
Some network services work, while others do not. For example, Ice Cold Apps SSH server does not work, while droid VNC server does.
From what I'm able to see, services that bind to "0.0.0.0" as the listen IP address work fine and are accessible from everywhere (NAT not withstanding), while services that bind to ":::" (IPv6) are only available from the phone itself (I test using ConnectBot's "telnet" mode). Such a service will respond to the phone's IPv4 address - when called from a local app - but will not respond to incoming connections from other devices on the network.
I don't have an IPv6 network that I can access, so I'm not sure if the problem is only for IPv4 devices or for all access.
I didn't have this problem with my previous phone - a Galaxy S2 running TouchWiz 4.1.2 or Cyanogenmod 11.
From looking at the output of iptables, I see there are many firewall rules, but I didn't see anything that should actually block content. I can paste the output of iptables if you guys want to take a look.
Any help will be much appreciated.

Which G3 do you have? I have a T-Mobile version and have noticed that the phones do not have IPV4 support on mobile networks, they instead do 6to4 to get IPV4 for apps. This does not happen on WiFi though. I'm trying to figure out if the G3 defaults to IPV6 only and even WiFi IPV4 services might be secondary to IPV6, so any app on the phone that is IPV6 ready will bind to the IPV6 interface and not listen on IPV4 for incoming connections.
You could try disabling IPV6 globally to see if this solves your problem. Not sure how to do it though.
I have the international G3 (LG-D855). I don't think my mobile network is using IPv6 (not that advanced - the IPv6 for rmnet0 is a zeroconf address).
Also, the situation is only interesting on WiFi, and I don't have an IPv6 wifi - so all traffic coming in should be IPv4 by definition.
