asp.net - How to limit web site access to USA or North America only

Question

This is a corporate site so Private. We want to limit access by IP address to USA/Canada or North America. Based on IP range, would allow user/pwd to get in otherwise -'no access'. Just trying to limit hack exposure from anything overseas.

Answer 1

Anybody who could get past your password security could easily get past any IP filtering security (and it may even be seen as a challenge, thus increasing the risk of overseas hacking). I think the premise of your question is flawed.
