root zone management
The Internet Assigned Numbers Authority (IANA) function related to the stewardship of the root zone. Root zone management involves maintaining the authoritative registry of the top-level domains (TLDs), coordinating with the operators of the TLDs, and managing the root zone’s key signing key (KSK).
Like all IANA functions, root zone management is performed by Public Technical Identifiers, an affiliate of ICANN.
