What is the stub zone in DNS?
A stub zone is a copy of a Domain Name System (DNS) zone that contains only resource records that identify the DNS servers for that zone. You can add either a forward lookup zone or a reverse lookup zone. You can add either an Active Directory-integrated zone or a file-backed zone.
Why do we need stub zone in DNS?
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. This does sound a bit like conditional forwarding, and actually, it is!
What are the 3 types of DNS zones?
Types of DNS Zones
- Primary zone.
- Secondary zone.
- Active Directory-integrated zone.
- Stub zone.
- Reverse lookup zone.
What are the three types of DNS records available with stub zones?
3 types of DNS servers—DNS Resolver, DNS Root Server and Authoritative Name Server.
When would you use a stub 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.
How do I create a DNS stub zone?
How to create a stub zone in Windows server 2016 DNS – YouTube
What is primary secondary and stub zone?
Types of DNS Zones
In the original implementation of DNS found in RFCs 1034 and 1035, two different types of zones were defined: Primary zones, which store their zone information in a writable text file on the name server. Secondary zones, which store their zone information in a read-only text file on the name server.
What is DNS zone example?
DNS zones are not necessarily physically separated from one another, zones are strictly used for delegating control. For example, imagine a hypothetical zone for the cloudflare.com domain and three of its subdomains: support.cloudflare.com, community.cloudflare.com, and blog.cloudflare.com.
Is stub zone an authoritative zone?
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.
What does a stub zone do?
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.
What is the difference between stub zone and conditional forwarder?
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 stub zones and scenarios to use it?

What is a stub DNS 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.
Is a stub zone read only?
A stub zone is like a secondary zone in that it obtains its resource records from other name servers (one or more master name servers). A stub zone is also read-only like a secondary zone, so administrators can’t manually add, remove, or modify resource records on it.
