It is very difficult to accurately identify
geographic locations
within the UK. IP addresses are generally assigned from an ISPs pool
which they use nationwide, so they just identify to wherever the ISP
is based.
Truth.
I just checked where
http://geoiplookup.wikimedia.org/ believes my (fixed) IP addresses
are. "Truro" is the response! (I'm actually just north of London).
Geolocation has been something of an interest of mine for a few years and whilst
sub-country details can be good in, for example, the USA, it is poor to useless in the UK
(and thus something I am working on improving). Some GeoIP services are more accurate for
me. IPv6, btw, will make the issue more difficult initially, primarily because of the use
of tunneling.
