I know that ISP's would log the IP address of users but how would they resolve the IP to an address?
cheers.

They can track you, because your modem has to be configured with either a serial number or with a username and password to establish the connection to your ISP.
For cable modems you might be interested in the DOCSIS standard. ADSL usually has a PPPoE connection with username and password.
