Install and Configure BIND 9 Master and Slave DNS Server for Local Network using AlmaLinux 9

In this video, I will show you how I installed and configured a DNS server for my local network.

The DNS server that I installed is the de-facto standard Bind 9.

I also setup two DNS servers as master and slave.

In the named.conf file.. did you leave "recursion" set to yes?

Can you create a video on LDAP? Looking into an alternative to AD. Salamat!

Well those are local netowrk ip's. But how you would setup 2 nameservers (master+slave) in real world with 2 different public ip's. You cannot create 2 nameservers for 1 public ip.
