Can I suggest you investigate dig and host. They make DNS querying much simpler.
Host:
$ host 168.209.115.218
218.115.209.168.in-addr.arpa domain name pointer mail.amorphous.net.
# Specified resolver:
$ host mail.amorphous.net. jupiter.is.co.za
mail.amorphous.net has address 196.211.13.115
Dig:
$ dig -x 168.209.115.218
