Netblock owner ... and location.

[vern]

I have a couple of questions ...

1. How do I find out the owner of a certain IP? or block of IPs?

2. Is there any way to find out where the IP is physically located? I'm assuming that knowing the owner of a certain IP block or IP could help, but there are companies that span multiple countries and own large class B addresses. I'm aware that one can find out the general location of some IPs by looking at their resolved host name ... but what about IPs that don't resolve?
