What is the purpose of a stub zone?

DNS stub zones are used to enable your DNS servers to resolve records in another domain. The information in the stub zone allows your DNS to contact the authoritative DNS server directly.

What does a stub zone consist of?

A stub zone contains: 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.

Secondary zones, which store their zone information in a read-only text file on the name server.

What is the difference between conditional forwarder and stub zone?

They are completely different. For one, Conditional Forwarding does not participate in zone transfers, while stub zones do. Also, with conditional forwarding, when a query is sent to the DNS server, it will perform recursion and get the answer to the query. With stub zones, a referral is given to the resolver (client).

What is a DNS stub resolver?

The DNS stub resolver is a component of the DNS that is accessed by application programs when using the DNS for e.g. resolving domain names to IP addresses. The stub resolver simply serves as an intermediary between the application requiring DNS resolution, and a recursive DNS resolver.

What is the difference between secondary zone and stub zone?

First, while secondary zones contain copies of all the resource records in the corresponding zone on the master name server, stub zones contain only three kinds of resource records: A copy of the SOA record for the zone. Copies of NS records for all name servers authoritative for the zone.

Do I need a DNS zone?

Can I mix DNS servers?

In some cases, a server can be primary for one zone and secondary for another zone. Although each zone is limited to one primary DNS server, it can have any number of secondary DNS servers. Maintaining one or more secondary servers ensures that queries can be resolved even if the primary server becomes unresponsive.
