About 15 DNS requests for 0.debian.pool.ntp.org every minute

Hi,

NCP sends about 15 DNS requests for 0.debian.pool.ntp.org every minute.
Also for ipv6, where no record exists for.
Why does it need check the NTP server this often?

Thanks and regards

Is NTP working?

timedatectl
timedatectl timesync-status

Is your host/environment solely IPv6, dual-stack, or IPv4-only?
