cache dns server

Current dns server default cache is 1 hour , should increase to 4 hour or 8 hour to improve performance dns ?

  • In my experience there's nothing that needs to be configured specific to your DNS server, but then again its a pretty vague question. When I stand up a new domain controller with integrated DNS role I don't do anything specific to DNS settings.

     

     

  • What is this DNS server being used for? Where are you looking at settings? What problems are you trying to solve?

        Hard to say really. I'd start by describing the environment and topology. Then also the problems you're trying to solve.
