Could someone please explain this nmap output?

Hi all, I have just taken out a lease on a dedicated web server and am beginning the process of learning about securing it and getting apache and php up and running.

I was keen to do a basic portscan on the ip to see what turned up and the results do not make sense to me.

I have executed an nmap scan of the IP addy that the host gave me and it produced the following results. Could someone please explain what the results for me:

Here I use a dummy/invented address space ip as an example and myhost.com as the domain for obvious reasons.

suppose I was given the IP 208.44.65.77

and so I executed nmap

First thing I don't understand is what is the meaning of resolving my IP as:

quote:
--------------------------------------------------------------------------------

Host 180.200.44.100.reverse.myhost.com (208.44.65.77)

--------------------------------------------------------------------------------


Is this how they have allocated my IP range via a firewall - ie is it within a DMZ or VPN or something to do with NAT?

I am on a steep learning curve but with a clear explanation of what is going on here I think I will catch on fast...

I appreciate any help offered.

Will
