Geotargeting IP to Country?

Question

I seen a couple of ways where you can whack a load of IPs in the database and then rip em back out again.

But what other methods are there?

Answer 1

Does not slow your website - because the data is calculated and pulled from the database. It does not go out of your site and do a whois if that is what your thinking.
So it's very fast.
