In this video, I have demonstrated how to install and configure Linux DNS Server. This is a complete Guideline for Linux DNS Server Setup.
The DNS server is extremely important for the network. Name resolution is not possible without DNS Server. All devices and servers, to some extent, do name resolution. Linux DNS Server Configuration is extremely simple, and I’ve illustrated to you how to do it step by step. DNS servers are classified as Primary, Secondary, or Caching Only depending on their configuration. A DNS server is called a primary DNS or master DNS server if it manages a zone or domain’s DNS Records. We can set up a Linux DNS server in failover mode so that if the primary DNS server goes down, the secondary DNS server will respond to DNS queries. As a result, the master DNS Server’s standby Replica is used as a backup.
And caching-only DNS is neither a master nor a slave; rather, it is a standard DNS server that responds to DNS queries and caches them, then responds from the cache when the same query comes up again. The default behaviour of all DNS servers is to respond from the cache; however, caching-only receives the query and also forwards it to an upstream DNS server, serving as a DNS Forwarder. All of the scenarios have been demonstrated to ensure that you have a thorough understanding of the DNS Server.
