If it doesn't have a DNS entry then NSLookup will not resolve it. Can you connect to it using the IP address in an RDP session?

I cannot connect with RDP. &nbsp;I can only connect with ftp to this ip address but do not have a login. I do not see any helpful info from the ftp output.<br />

There may be an entry in DNS. &nbsp;Forward lookup, from a hostname to ip, may work in nslookup but reverse lookup may not be setup.

Just to clarify we are talking about external DNS rather than internal?

<div class="content wysiwyg-content">
I have an IP address (sorry I cannot give it out) which I need to resolve to a hostname. &nbsp;'nslookup' cannot resolve the IP address.<br />
<br />
I ran a whois which gave me an IP range for the owner. &nbsp;It does not tell me the domain name for the set of IP range. Was thinking about dumping out all available hostname for that domain but not sure if this will work.<br />
<br />
<br />
What can I do?<br />
<br />
Thanks

What is the hostname?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
