Windows Command to find the hostname for an IP address

JdS · #1 21-Jul-2007, 22:30

What is the Windows XP command, if any, to find the hostname for a given IP address?

I can do the reverse with `nslookup`:

Code:

C:\Documents and Settings\J>nslookup yumie.gidnetwork.com
Server:  cns3.tm.net.my
Address:  202.188.0.133

Non-authoritative answer:
Name:    yumie.gidnetwork.com
Address:  69.30.244.34

... but I don't know how to find the hostname if all I have is an IP address.

The command is called reverse DNS lookup. If you want an Internet site, try this site: http://remote.12dt.com/.

According to this site (http://www.tech-faq.com/reverse-dns.shtml), your nslookup command should work just fine w/ the IP address. Otherwise just do Google search on reverse DNS (rDNS).

You could give this a try,
www.php.net

A few more using different methods,

Yes, it works!

I don't know why I didn't try it before posting. Thank you.

As for the links to online tools, I don't know why anyone would use a web site to get this information when there is a command like nslookup in your PC already.

Only the first list one is like that. The 2nd is code, 3rd a tool, and fourth is code (granted a form a basic) but using Winsock.

My money however was on the php.net link. I apologize for missing the target.

With PHP, the code to create a web page/tool like this is rather trivial e.g.

PHP Code:


<?php

if( isset($_GET['ip'])  &&  $_GET['ip'] )
{
    echo "IP: ", htmlspecialchars($_GET['ip']), " is ", gethostbyaddr($_GET['ip']), "\n";
}
?>

is pretty much all it takes!

All this time I have been using Linux's host command to get this information and it never occurred to me to figure out how to do this with Windows -- until today!
