Re: Computer Name from IP

Sorry, I should have mentioned that in order to get some of these utilities
to work in Windows, you would need to install additional tools like
Ethereal. Also, netstat -a should already give you the reverse DNS name if
that is available. So, you aren't seeing it then DNS probably won't help
you. The other tools I mentioned may not help much either if the IP
addresses you see are on a LAN. You might try using the "finger" utility
decribed in the RFC.

There are a few different ways of determining ownership information for IP
addresses. Some common ones are:

1. whois
Ex: whois -r 128.117.0.0 @whois.arin.net
Ex: whois -h whois.arin.net 128.117.0.0

2. DNS
Ex: nslookup 128.117.0.0
Ex: dig -x 128.117.0.0

3. routing registries
Ex: whois -h rr.level3.net 128.117.0.0

The problem you run into is that entries aren't always present, and/or
aren't always kept up to date. Have a look at the RFC below for some
ideas.

Hi All,
I dont know if here is the true place for my question. I want to learn
the name of the computers connecting to me. I am writing netstat -a in
command window and I can see the ip of the connection. But I want to
learn who he is. How can I do that?
Ragards...
