I need to change my isp address........
My questions are -
1. If I change the name of my computer under system info will that
change my isp address?
What do you call "my isp address"? Your name of your computer will change
nothing external to the computer. Tell us what problem you are trying to solve, not your guess at a solution.
2.Is my isp address different when using different wifi connections?
Yes.
3.How do I change my isp address with my t mobile phone as a modem??
Would changing my cell number change the isp?
No
4.Is my email account through yahoo registered under my isp address.?
We have no idea.
I presume you mean your IP (internet protocol) address.
ISP stands for Internet Service Provider.
Every packet you send and receive over the internet contains source and destination IP addresses and port numbers, which may be recorded by a web server you visit, and should be recorded by your ISP.
No, in the majority of cases your IP address is assigned by the ISP when you connect, and represents your electrical location on the network, not your computer. With a fixed line account you may have a fixed personal IP address, or one may be dynamically allocated from a pool whenever you log on, but it will remain fixed for the session, and you can bet your @ that the ISP (in this case T-Mobile) keeps a record of which user account had which address at any given time. I'm pretty sure that's part of the data they are legally required to keep, under European law anyway, may be different in the US.
With public WiFi I think that usually goes through a sub-net using Network Address Translation (NAT), which effectively means all the customers appear to have the same IP, although different (dynamically allocated) port numbers. There's no way a web server could trace requests directly back to your computer or home address, only to the café, but the café could have (should have?) logged the allocated port number against your computer's (or WiFi adaptor's) unique MAC identifier and any account information they have for you.
As your IP address is not a constant there is no way it can be registered against your Yahoo account.
As for changing your T-mobile IP, that is between you and T-mobile. It may well be that you get a different one every time you call. If they have allocated you a "static IP" then it would be attached to your account you'd have to ask them to change it, or open another account with another phone. But they will still be able to trace it back to you e.g. through the credit card you used to buy the phone.
If you are using Windows XP, then you can find out your current IP address at System Information (in Accessories / System Tools), selecting "Internet settings, Internet Explorer, Connectivity. Scroll down to "Use server assigned IP address" (e.g. Yes) and "IP Address" (e.g. 192.168.16.10); and answer your own question. NAT subnet addresses begin with 192.168 or 172.(16-31) or 10.
If you are trying to evade the long arm of the law, then you need to keep abreast of developments, as governments are very keen on developing these monitoring techniques, under the pretext of chasing terrorists.
