Reverse DNS lookup is checking an IP against a domain name server and being able to retrieve the corresponding domain name. For instance, a reverse DNS lookup lets you tell that the IP address 209.41.183.225 is actually http://hostmysite.com. (check out www.dnsstuff.com to run Reverse DNS lookups).
