nsupdate

From Wikipedia, the free encyclopedia

nsupdate is a computer network maintenance utility used by network administrators to request the name server of a DNS zone to update its database. The name server might be local to a domain or, with appropriate authentication and permission provided by DNSSEC, an internet name server.

BIND 8 and later supports this feature.

# nsupdate
