What is Stub Zone in DNS Server?
A stub zone is a copy of a zone that contains only those resource records necessary to identify the authoritative Domain Name System (DNS) servers for that zone. A stub zone is used to resolve names between separate DNS namespaces. This type of resolution may be necessary when a corporate merger requires that the DNS servers for two separate DNS namespaces resolve names for clients in both namespaces.
A stub zone consists of:
- The start of authority (SOA) resource record, name server (NS) resource records, and the glue A resource records for the delegated zone.
- The IP address of one or more master servers that can be used to update the stub zone.
The master servers for a stub zone are one or more DNS servers authoritative for the child zone, usually the DNS server hosting the primary zone for the delegated domain name.
