Re: Do IP addresses map to MAC addresses?

Well, not quite, an IP address is assigned to you by a DHCP server which notes your MAC address and gives you the same address the next time you login.

So for the most part it is the same IP address you get every time.

However the DHCP server has a timeout - so that if for example you leave NTL etc all the IP addresses arent taken up.

So if you didnt use your PC for a while (and i dont know how long this is with NTL) you could log in and get a different IP address as the timeout would have expired.

Either way your IP address and MAC address is logged.
