TLD Nameserver

Holds information about all domains sharing the common TLD

  • ex. a com TLD nameserver contains information for all the .com sites.

When queried, the top-level nameserver returns the names and addresses of the nameservers that are authoritative for the second-level zone that the domain name ends in (e.g. facebook.com)

broken into 2 groups:

1. Generic TLD, like .com, .org, .net, .edu, and .gov.
2. Country code TLD, like .ca, .uk
  • overseen by IANA (a branch of ICANN)
