If DNS lookups have a significant effect on search time, there is
something badly wrong with your DNS setup. DNS lookups on domains
under your control should be lightning-fast.

Using IP addresses in configs is a false 'economy' - when you need to
re-organise your servers you will have far fewer options if everything
has fixed addresses wired into the config. It will also prevent you
from using TLS properly.
