I was driving home last night and thinking there has to be a
mapping of IP to city/location (even if it does change
slowly with time). You'd think ICANN (or whoever) would be
required to release this info as part of their monopoly on
the internet. The FCC is required to release the frequency
and location of TV and radio stations. Horm's Saru sure is a
lot of work to get information that should be public domain.
I see the real version (geocity) is $370.
Not perfect - nothing like this is - but definitely a
functional optimization. My applications so far are to
direct clients to the "nearest" web server cluster and VPN
gateway for the purpose of minimizing latency.
OK
I stuff the names to be geo-balanced into a subdomain
served only by a group of nameservers running the above
code and database.
"the names"? is this the names of your clients or your
servers? Not sure what you're doing here. I assume if I'd
installed geodns, I'd know what you were doing, but I don't.
Do you have a mapping for all IPs (even if it isn't real
accurate)? If not, what do you do with someone from an
unmapped IP?
