DNS stands for domain name system. DNS translates domain names into IP addresses and reverse DNS translates IP addresses into domain names. This is necessary because computers use IP addresses while people use readable names. Forward DNS is set up through your domain registrar. Reverse DNS is set up through your internet service provider (ISP). Without reverse DNS, some internet and e-mail functions will not work. Often reverse DNS is neglected when setting up a network.
