On my home network, I have my firewall providing NTP

host name, which will return both IPv4 and IPv6 addresses. In
watching the NTP traffic between my desktop computer and firewall, I
see both IPv4 and IPv6 addresses alternately being used. Is this the
way the NTP client normally works? I could understand it trying
multiple addresses, if that is what I provided, but I only provide a
single host name, that returns both IPv4 and IPv6 addresses.
Normally, with other apps, IPv6 is preferred over IPv4.
I have never looked at the traffic, only at the output of 'ntpq -pn' -
sometime I see ipv4, some times I see ipv6.
