Description: Domain Name System (DNS) Structure and Delegation provides some information on the structure of the names in the DNS specifically the top-level domain names and on the administration of domains. The Internet Assigned Numbers Authority (IANA) is the overall authority for the Internet Protocol (IP) Addresses, the Domain Names, and many other parameters used in the Internet. The day-to-day responsibility for the assignment of IP Addresses, Autonomous System Numbers, and most top and second level Domain Names are handled by the Internet Registry (IR) and regional registries.
