Methinks the problem is all the web sites that claim to be able to locate
you when all they've got to go on is the IP that your ISP has currently
assigned to you. This is necessarily forwarded to them by your software
(without it, servers wouldn't know where to send the data you requested).
That unique IP tells them which ISP you use and probably the location of the
gateway to which you're currently connected---that is, in simple terms, the
equipment that currently connects your telco-provided DSL connection to your
ISP's internal network. But that doesn't necessarily tell them much unless
you use a tiny ISP that only serves a small area; neither telcos nor ISPs
want your data to travel via the shortest route to the nearest gateway; they
prefer their equipment to direct your connection via whatever is currently
the most under-utilised (or should that be *least over-utilised*) route,
even if it turns out to be very much longer in geographic terms.
I currently use one of the UK's larger ISPs which provides me with a
non-fixed IP and links to my PC via British Telecom's ADSL network. I live
in the UK West Country, but my ISP has no gateways in that region, so the
so-called location services never in fact place me within a hundred miles on
my home. Usually they think I'm either in Leeds or Sheffield (in the north
east of the UK) or in the London area (south east). It changes from time to
time, as a different gateway is likely to be auto-allocated by
load-balancing algorithms each time I reboot my ADSL router (or power it off
and on again).
[note: ADSL, which most UK users are stuck with whether they like it or not,
is *asymmetric* DSL---which is telcogobbledegookspeak for a DSL connection
in which upload speeds are massively throttled in comparison with download
speeds. I get up to 17Mbps down, but a max of only around 0.9Mbps up.]
