Her in teh UK its totally ointless, as addresses may be dynaicaly
allocated out f a pool of thousnds to any given cutstomer.

And it gets worse, because the link between te ISP and the customer is
over ATM and ADSL, so the last known location is the ISP's termination

Lookups will return London, Manchester or Glasgow and that's it.

Looking up mine will return a location 70 miles away.
