BT Broadband IP Adresses

I joined BT on 02/11/07 after transferring from AOL to get better internet speeds since I joined BT I have had at least 8 different IP addresses can anyone explain why. Also their speeds are all over the place. Thanks in advance for your comments

they use dynamic IP addresses, so each time you disconnect and reconnect you may get a different one.

The reason for the difference is that with some ISPs a dynamic IP address is more 'sticky' than others. In other words some ISPs remember the IP address they last gave you, and re-allocate this address to you the next time as long as it hasn't been re-assigned to somebody else in the meantime. Other ISPs don't do this and you get a random new address from the pool each time. Nothing to do with speed though.

PS - and of course some ISPs allocate you a static IP address that never changes.
