Nope, and even then it is not accurate. For instance, all AOL users
show as coming from Virginia. And when I'm on my dialup account from
MD, it shows I'm coming from NY.
You can get a state (or, as in the case of the Washington, DC area, a
metro area) in maybe 70-90% of the cases. But the more accurate you try
to narrow it down, the less accurate your location will be.
