Funny this should come up...
I've found that a local Mobile Broadband outfit here in NZ are using an IP
range that Akamai's Geolocation service thinks is actually in New Jersey.
Causes me some oddness as a result - this despite the fact that Maxmind
has it correct.
Whilst investigating this (just the day before yesterday) the following
URL came to my attention - allows you to check the IP you're on against
Akamai's Edgescape product:
http://www.akamai.com/html/technology/products/personalization.html
Their customer care team were responsive to an email I sent them (but were
unwilling to make changes without the request coming through their
customer... which in itself seems mad, their info is wrong - why don't
they correct it?)
Geolocation is clever, but seems to be very retrospective, and very much
an imperfect science... there should be some obligation on people offering
the service to work very hard to keep their data current, given the effect
it can have on an end user.

Maxmind www.maxmind.com is a fairly good indicator of what geo-locators are
seeing, but I recall a recent thread here that there have been disagreements
between the various geolocation services.
I think that some of it depends on the reference sources i.e. how many and
what the algorithms are and also the update frequency. Using plain old whois
data, for example, is notoriously unreliable, but definitely "usable" as a
reference.
Might be nice if search engines and cdn's had a verification site for
checking and suggesting corrections i.e.
www.favoritesearchengine.com/ipverifiy

IP2Location and Maxmind are mostly correct, but there appears to be no way
for me to verify that Google and Akamai have 96.31.0.0/20 listed
correctly.
Perhaps someone can point me in the right direction so I can make an
authoritative check.
Thanks,
