i did an nslookup of an ip address of someone trying to hack me and i get the following:

adsl-xxx-xxx-xxx.sdf.bellsouth.net

the x's represent the partial ip address

i would like to know the following:

is there any way this could be a proxy server?

what does the sdf portion stand for?

i did an ip2location on this address.  what is the probability that the state is accurate?  or could this be some main server?

any information would be greatly appreciated.

it can be a proxy server, but most likely it's a pc connected through DSL broadband connection to bellsouth.net ISP
Try to contact the ISP (of that hacking address), i think you should be able to file complain to them.

Yes.  Or some poor shmuck's box that has been hacked to function as a proxy.

It's a subdomain of bellsouth.net.  It stands for anything BellSouth decided they needed to structure a subdomain for.  You might have to ask them, and they might not want to tell you.

50-50.  IF BellSouth allocates addresses by region (probably a good idea, but there could be exceptions) AND IF the ip2location database knows about their allocations (and is up to date), THEN it might be possible.  But there's every chance that this just found the location of the administrator who registered the net block.

> or could this be some main server?

Fairly unlikely -- it looks like an ADSL client name.

Have you tried a traceroute to the address?  These kinds of client names often don't show geographical info, but router names often do, and so you may get a general sense that way of where the machine is located.  (ip2location may do this internally, or may not.)
