I have an IP address, xx.xx.xx.xx, for which ping works. But when I do an nslookup for that IP address it is failing. Is there a way to find the domain name of the machine with the IP address xx.xx.xx.xx?

The only way to do this is via a reverse DNS lookup. However, if you are saying that nslookup is failing then (unless there is a local issue with you having bad DNS servers listed on your local machine), then a reverse lookup will not work.
The various tools that other posters have mentioned, all ultimately do exactly the same the nslookup will do from your machine. They do a reverse DNS lookup via the "in-addr.arpa" address range (this is a special domain reserved in DNS for reverse lookups).

You need to use a "reverse DNS lookup". Try this one online, or Google further for other options.

Yep, it's called Reverse DNS! Perhaps try: http://remote.12dt.com/
Also consider DNSStuff: http://www.dnsstuff.com/ great website for troubleshooting DNS issues.

In order for an IP address to resolve to a hostname, a PTR record must exist in DNS. For example:
234.9.96.65.in-addr.arpa. 3570 IN PTR h00c0f06bacf1.ne.client2.attbi.com.
The ISP that owns the netblock including your IP (or its delegated zone authority) must set this up.

I doubt this will work. nslookup is doing exactly this type of reverse lookup when yu type in an ip address. Unless there is a local issue on the client with DNS entries, it will yield the same results. – None – 2010-01-05T13:19:25.823
