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. This does sound a bit like conditional forwarding, and actually, it is!

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).

How do you set up a stub zone?

Since the target is a forward lookup zone, right click on Forward Lookup Zones and select New Zone.Click Next on the welcome screen that appears.Select Stub Zone on the zone type selection. You can also tick on Store the zone in Active Directory to make this zone replicated to other DNS server.

What is a stub zone used for?

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.

What are secondary zones?

A secondary zone is a read-only copy of the primary zone that is stored on a different server. The secondary zone cannot process updates and can only retrieve updates from the primary zone. Secondary zones are organized within DNS views.

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.

What is primary secondary stub and integrated zone?

Stub Zone:- This DNS server must have network access to the remote DNS server to copy the authoritative name server information about the zone. AD Integrated Zone:- When you store a primary zone in AD DS, the zone type is changed from primary to Active Directory (AD)-integrated.

What is difference between forwarder and conditional forwarder?

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.

What is conditional forwarder zone?

Conditional forwarder can be used to send queries related to certain domains to your specific domain name server,whereas forwarder is used to forward all the queries from AD DNS to the domain name server.

What is a stub zone and how can a stub zone be used?

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.

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.

How do I make a 2019 stub zone?

Is stub zone authoritative?

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 are primary and secondary zones?

There are two types of DNS zones u2013 Primary (Master) DNS zone for control and Secondary (Slave) DNS zone for redundancy and better performance. The first contains all the original DNS records, and the second gets them from the Primary DNS zone. The process is called DNS zone transfer.

What is the purpose of a secondary zone?

Secondary Zones are a DNS feature that allows the entire DNS database from a Master DNS server to be transferred to the Secondary. A Secondary Zones allows an organization to provide fault tolerance and load balancing to internal names.

What is primary zone and secondary zone 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 a secondary lookup zone?

We also have what’s referred to as the Secondary Zone. The Secondary is also an authoritative DNS server that allows us to be able to read the database file from another DNS server, but it’s going to be a readu2011only version. This is going to provide for fault tolerance.

Why stub zone is used?

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 integrated zones?

An -Active Directory-integrated zone is a primary DNS zone that is stored in Active Directory and thus can, unlike all other zone types, use multi-master replication and Active Directory security features. It is an authoritative primary zone in which all of the zone data is stored in Active Directory.

What is AD integrated zone?

AD-integrated DNS zones are stored in directory partitions within Active Directory. These directory partitions replicate along with the rest of AD; therefore, no extra configuration (i.e., zone transfer setup) is required for DNS replication. Further, AD-integrated zones allow the use of secure dynamic updates.
