Subject: [ntpwg] NTP daemons and DNS (question)

Hi,

I'm trying to understand how various NTP daemons handle DNS.

Will they perform a DNS lookup each time they are about to poll a
server?

Or do they lookup and store the IP address of an NTP server in ntp.conf
once when they start and keep using that forever?

Or something in between perhaps?

I tried to figure this out with TCPdump, but my findings where not
conclusive enough.

Thanks.
