Q:

BIND DNS SERVER in my Production environment

I would like to start working with a local DNS server in my production.
right now instead of working with DNS I'm working with IP Addresses.
I would like to know what is the effect of working with DNS Server instead of IP Addresses.
can it cause a real Overhead in my network?
which DNS server do you most recommend to work on Centos Linux?

A:

Using DNS in a local network will usually not create any noticeable overhead, as long as you allow for a TTL greater than zero. This will mean that the clients cache the entry and don't ask again for the duration of the TTL. If your entries are long-lived, using a TTL of one day (86400) is not uncommon.
