As far as I know, for regular server entries once it's done the
initial lookup on startup, that's it...

I believe for pool entries it will do a lookup to grab new IPs if a
pool server goes silent. Maybe that's what you were referring to?

I'm sure Harlan or Miroslav can give us a definitive answer.
