For work, I implemented an expanded variation of this:
http://www.caraytech.com/geodns/
...and using this database get pretty accurate IP-to-US state mappings,
in addition to country:

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. I stuff the names to be geo-balanced into a
subdomain served only by a group of nameservers running the above code
and database.
