HILF,
I sometimes see popups, etc. that have accurately pinpointed my physical location.
This is because you have been assigned an IP address by your ISP, either fixed or DHCP. It is only this IP address that is providing location information, and even that is of your ISP local router, not yours.
It is possible to sign up with an internet proxy, so that all your web traffic appears to originate from the proxy address. Google "anonymous surfing" for more.
But that has nothing to do with email.
What do you want to change in your email address? You can go to any number of free providers like hotmail, gmail, yahoo etc. etc. to get a completely new email address.
You can almost certainly add an "alias" to your existing email account, so that emails to the alias arrive in your existing mailbox. You can probably also set up an additional mailbox with your ISP - NTL is the same as Blueyonder and Virgin now, and with blueyonder I have 5 mailboxes. Obviously all these options would still leave you with a
[email protected] email domain name.
Finally, you could choose and register your own domain name, which then allows you to configure any number of email addresses for that domain, and have all emails to that domain forwarded to your existing NTL address.
