Domain Name Server, termed as DNS in short, are servers with a specialized task of translation (resolution) of humanly memorable domain names and hostnames into the corresponding numeric Internet Protocol (IP) addresses, the second principle Internet name space, used to identify and locate computer systems and resources on the Internet.
DNS Servers allow the Internet to go human-friendly and increase its usability. They are generally maintained by your ISP’s although there are public DNS server applications like OpenDNS and Google’s Public DNS as well.
