DNS Common Uses

Just as IP is the most common network layer protocol, DNS is the most common session layer protocol. Although IP provides address support between networks, DNS provides memorable hostnames and meta-information for other network services. Nearly every network-enabled application supports hostname lookups through DNS servers. The most common uses for DNS are hostname-to-address mapping and mail server identification. DNS can also provide additional information about hosts and domains.
