This is a bit off topic, but I was hoping someone could at least point me in the right direction. I regularly check my security logs to see who's been trying to get in and I'll do an nslookup on any IP address that occurs over 3 times. Now once in a while this will actually be useful and I come up with actual useful information. But most of the time I end up with what I started with, an IP address. Is there a way to find out who owns what block of addresses? Also is there a way to find out the real IP address if someone is spoofing (quite often we are probed by someone with a 10.x.x.x address)? Finally, is there any kind of SOP when dealing with unauthorized attempts from foreign countries (we seem to get probed quite a bit from SE Asia)? Any information would be helpful.
