Why is DNS considered one of the “pillar” application layer protocols?

The Domain Name System (DNS) is one of the pillar application layer protocols because it performs names resolutions by converting symbols into numeric addresses based on a Standard Name Resolution technique. The technique enables the translation of DNS names which are taken as input and resolved into the corresponding Internet Protocol (IP) addresses. DNS also performs Reverse Name Resolution and Electronic Mail Translation on the application layer. DNS functions on the application layer by defining the network service based on a message format. In that case, a user can manually query the name revolver using the nslookup utility found in the operating system.
