What’s difference btw master and slave DNS server?

What’s difference btw master and slave DNS server? The main difference between master and slave DNS server is that the master DNS server reads the domain zone related data and communicates with the slave DNS server while the slave DNS server is a server that gets the zone data. from the master DNS server immediately after it is configured.

DNS is a server that converts domain names to corresponding IP addresses. The DNS server can be a master or slave DNS. The server administrator can configure a DNS to be master or slave. A DNS zone is a container of DNS settings and records for a DNS namespace. In addition, it is also possible for a single server to function as a master and slave server. It can function as a master server in one zone while working as a slave server in another zone.

What is Master DNS Server?

The master DNS server is also known as the Primary DNS Server . Read data related to the domain zone. It also communicates with slave servers. The server administrator instructs the servers how to communicate with other web servers. A master server that communicates with the slave server is called a zone transfer .

Each domain name on the network is assigned to DNS servers for redundancy. This process simplifies the task of server administration. If a primary server already contains zone data for a domain, there is no need to replicate this data. This is because the DNS master and slave continually share zone data. When there is a request to a server, it first travels through the master slave. Then the master slave will assign functionalities to the slave server.

What is a slave DNS server? What’s difference btw master and slave DNS server?

A secondary DNS server is also called the slave server. Once configured, it receives zone data from the master server. Every time the slave DNS server works, it gets data from the master DNS server. Slave DNS servers are also important as master servers. This is because they offer security through redundancy. Also, slave servers minimize the load of requests on the master DNS server.

Difference Between Master and Slave DNS Server

Definition What’s difference btw master and slave DNS server?

The master DNS server is a server that stores the original copies of all zone records. In contrast, the slave DNS server is a server that uses a special auto-update mechanism to communicate with the master server to maintain an identical copy of data similar to the master server. These two definitions explain the basic difference between master and slave DNS server.

synonyms

The primary DNS server is called the primary DNS server, while the slave DNS server is called the secondary DNS server.

Number of DNS servers

Each zone can only have a single master DNS server, but can have multiple slave DNS servers. This is another difference between master and slave DNS server.

Data

Also, an important difference between master and slave DNS server is that the master server gets information directly from local files. On the other hand, the slave server contains read-only copies of the zone file, and obtains data by communicating with the master server.

Use

Also, the main difference between master and slave DNS server is that the master DNS server hosts the control zone file, which contains all the authorized information of a domain. However, the slave DNS server provides redundancy when the master slave goes down. It also reduces the request load on the master DNS server.

conclusion

In short, a DNS server can serve as a DNS master or a slave. The main difference between master and slave DNS server is that the master DNS server reads the domain zone related data and communicates with the slave DNS server while the slave DNS server is a server that obtains zone data from the server. Master DNS immediately after setting up.
