What is primary zone and secondary zone and stub zone?
A zone is a contiguous portion of DNS namespace managed by one or more name servers. 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 forward zone and reverse zone in DNS?
Forward lookup zones resolve names to IP addresses and Reverse lookup zones resolve IP addresses to names. ☑ Forwarders can be used on your DNS server to forward requests for which your DNS server does not have an authoritative answer.
What are DNS stub zones?
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.
How many zones are there in DNS?
DNS Zones and Domains A domain administrator would be responsible for creating zones, and delegating responsibility for these zones to an administrator and DNS server. To illustrate we will refer to the diagram below which shows a section of the domain name system which has been divided into 3 zones.
What is DNS secondary zone?
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. Create a DNS view or click an existing DNS view.
What are domain zones?
A “domain” represents the entire set of names / machines that are contained under an organizational domain name. For example, all domain names ending with “.com” are part of the “com” domain. A “zone” is a domain less any sub-domains delegated to other DNS servers (see NS-records).
What are the three types of DNS records available with stub zones?
DNS servers cooperate to accurately resolve an IP address from a domain name. In step 1, the stub resolver at the host sends a DNS query to the recursive resolver….The three DNS server types server are the following:
- DNS stub resolver server.
- DNS recursive resolver server.
- DNS authoritative server.
What is DNS type A?
The “A” stands for “address” and this is the most fundamental type of DNS record: it indicates the IP address of a given domain. For example, if you pull the DNS records of cloudflare.com, the A record currently returns an IP address of: 104.17. 210.9. A records only hold IPv4 addresses.
What is a primary zone DNS?
Primary DNS Zone: A Primary DNS zone is the original Read-Write Authoritative DNS zone of portion of a DNS Namespace. When a DNS Server hosts a primary zone, that DNS Server is considered as the Authoritative DNS Server and it is the primary source for information of that zone.
What are DNS stub zones in Windows Server 2003?
Stub zones are a new feature of DNS in Windows Server 2003 that can be used to streamline name resolution, especially in a split namespace scenario. They also help reduce the amount of DNS traffic on your network, making DNS more efficient especially over slow WAN links.
Where is the secondary zone located in DNS server?
The zone data is stored in a text file located in this folder c:\\windows\\system32\\DNS on the Windows server running DNS. A secondary Zone is a read-only copy of the primary zone. This zone cannot process updates and can only retrieve updates from the primary zone.
What do you need to know about DNS zones?
DNS Zones store DNS resource record information. Some common DNS records include: There are many more record types, and without these records, everything would be accessed by an IP address. DNS Zones provide us a way to maintain these records on one or more servers. Let’s take a look at the different zone types.
How are DNS zones replicated in Active Directory?
Integrated zones can be replicated to all domain controllers in the domain and forest. Active Directory integrated zones use multi-master replication, this means any domain controller running the DNS server service can write updates to the zone for which they are authoritative.
