DNS is a distributed Internet directory service. A network of DNS servers respond to requests to translate between domain names (such as dmoz.org) and IP, Internet Protocol, numeric addresses (such as 188.8.131.52) for URLs and email delivery. Most Internet services rely on DNS to work.
DNS stands for Domain Name System. It is an application layer protocol.
ADNS is a free resolver library for C (and C++) programs, released under GNU's General Public License.
