Well, it turns out my global IP changes totally at random.  It's almost like I have two IPs leased to me and I'm switching between them.  One being in the 12.*.*.* and one being in the 65.*.*.* range.  I'm having trouble using some services this way and my ISP is basically ignoring me.

Any suggestions?

How often (roughly) does it change?

It can change with a simple refresh of a page.  It changes every few seconds it seems.

A) how are you determineing this? and
B) why is it a problem?

A) how are you determineing this? and
B) why is it a problem?

A.)  Ipchicken, forum posts, and some other site I can't remember.
B.)  When hosting a game server or trying to play a game that has a system that checks your ip constantly, I get wonderful problems such as "IP Address Mismatch" errors and such.

If these are IP addresses issued to you by your ISP, then they are the only ones who can fix this problem.  Something tells me though that the lease time for the IP Address is set to expire almost immediately, which is very strange indeed.  Usually a lease can be either one day or one week, for me my lease on my IP address is set to expire after 4 days.  Put simply, if you only want one IP address, they have to go into thier tables and fix this problem.  Call them up if you have to, because dealing with issues like this via email is damn near impossible. 

If you're using XP, you can use ipconfig/all to view your lease length.  be sure to run the command prompt first, then type in the command, otherwise it will close so fast you won't see it.

Oh, with ipconfig it always indicates I'm using one IP address.  Only when I use some external source does it report two different ones at times.

It usually says my IP should be leased for a day.  It's also always in the 12.*.*.* range.

If ipconfig is giving you a different IP than what a forum (external source) IP then it sounds like your ISP is doing some NATing.

[Descenterace]

So your IP is not actually changing. The problem is likely that it's not doing NAT correctly, or the web services you're using are checking your IP in strange ways.

I like where I live. I don't want to move.
