rdns is the mapping of an ip to its hostname.
coldfire at slimer:~$ host google.com
google.com has address 216.239.51.100
google.com has address 216.239.33.100
coldfire at slimer:~$ host 216.239.51.100
100.51.239.216.in-addr.arpa domain name pointer www.google.com.
coldfire at slimer:~$
the second is an example of the rdns mapping.
