Domain Name Services - Internet Assigned Numbers Authority

WEBDomain Name Services. We operate and maintain a number of key aspects of the DNS, including the root zone, and the .int and .arpa domains. The root is the upper-most part of the DNS hierarchy, and involves delegating administrative responsibility of “top-level domains”, which are the last segment of a domain name, such as .com, .uk and .nz.
