[clug] [slightly OT] how to find what an IP is

[James McNeill]

It depends on who the domain is registered with as to who you need to 
look up the address with. a good place to start is www.arin.net .

from there you should be able to find where to go, if it doesn't have it 
there. The 81.52.248.151 ip is registered as being in amsterdam. You 
might want to try a traceroute on some of those ips to see what network 
they come from.

If the domain was regstered in australia, you'd be able to find more 
info on it at www.auda.org.au (the .au domain admin site). and so on and 
so forth for all top level domains respectivly.  don't know who the 
domain registrar for the netherlands is. Ask Google, she'll know.

if you want to chase things from ground up www.iana. (net or org, don't 
remember which, can't be bothered opening a browser ;-) has all the 
rules regarding IPs on the net, and some good links. If you're still 
stuck on a windows box but want to find out more about these addresses, 
there are a few sites that let you do an online nmap of an address. 
ooops, did I say that?
