Dumb question. I want to create a DNS server for my private network so I can resolve private IP's in my network, how is that done? This is not for external use, internal only.

Hi this look easy but after I installed my pi, it was not the same, tried your description. But couldn't make it work You wouldn't be able to make one for raspberry and get it to work

[@ranjithar9450]

Does it configure DNS root, authoritative and tld server?

[@Akshay-xx7rg]

86400 seconds is just one day, not 60 days.
