[Intrusions] Locating IP Blocks Quickly

[Allen Mundt]

I hope that this question is not too basic, but does anyone know of a quick way to grab the first three octets of an IP address and figure out where that is (like what country it is in)?  I know how to do a whois, but an IDS returns so much stuff, I would like to know if there is a quick way to map it out.

Thanks

Allen
