Last week I moved from Vodafone to Telecom XT and I have noticed ever since that while using my mobile or tethering through it that my IP address constantly changes on each page I visit (and even on a page refresh). I used a web site www.whatsmyip.org and I saw my IP address as:

222.153.223.32
222.153.223.33
222.153.223.34
222.153.223.35
222.153.223.36
222.153.223.37
222.153.223.38
222.153.223.39

I see the IP address changing even when I just refresh the web page each time.

It looks to me like I am being round-robin proxied through a farm of web caches.

However, this causes major problems with logging into web sites with my sessions consistently being lost due to my IP address changing as I navigate through a web portal such as webmail, online banking etc.

Is anybody else seeing these issues on Telecom XT? I can't believe nobody else is not being affected by these issues and also experiencing issues with login/sessions to web sites etc.

Sounds like the GGSN doing something funky

If you use the APN internet.telecom.co.nz you should be ok. The wap.telecom.co.nz APN changes IP on every single request.

I have complained about this a couple months ago when I implemented a feature on Geekzone to logout a session if the IP changes. After much investigation, the result was nihil.

Smells like non persistent proxy behavior to me.

Geekzone would be one, if you turn on the option to protect your IP address. Go on, you can try yourself ;)

Yes any web site it seems.

Some useful ones which will tell you your IP while you browse:

http://www.whatsmyip.org/
http://www.ipchicken.com/
http://www.ipmonkey.com/
http://speedtest.net/

In particular I am trying to login to 2talk's portal at:

https://live.2talk.co.nz

However, a session is logged out if the IP address changes during that session for security reasons. This happens all the time on 2talk's portal.

By the way switching my APN to internet.telecom.co.nz fixed the issue - so thanks for that. However, I expect lots of people will be configured to use the wap.telecom.co.nz APN. Also, I know that MVNO's such as CallPlus use www.callplus.net.nz as their Internet APN and this also suffers the same issues as the Telecom wap APN - so it affects more than just Telecom XT customers.

Maybe slightly off-topic but I don't get this on Vodafone 3G. Though I do get the message every time I reconnect as the IP changes, so it definitely appears to be an XT issue.

It's quite off topic. This is a XT "feature", and only in one of their APNs, as reported.

Sounds to me like its load balancing.

Does your XT device get a public ip direct to the device, or is it getting an internal XT natted address and getting changed to a public one via one of the load balancers?

Yes the IP address given to my phone is not the same as the IP address I see when browsing a web site so it is almost certainly passing through a web proxy - or rather several web proxies. The problem is that the load balancing is not keeping my connection through the same proxy - so each page I load passes through a different proxy and my IP address changes.
