[Message part 1 (text/plain, inline)]
On an IPv6-only network, the default configuration for ntp-service-type
doesn't work, because the default pool used (<0.guix.pool.ntp.org>)
doesn't have IPv6 addresses.
In fact, the <1.guix.pool.ntp.org> and <3.guix.pool.ntp.org> pools don't
have IPv6 addresses either. Only the <2.guix.pool.ntp.org> pool works
with IPv6.
Would it be possible to add IPv6 support to pools 0, 1 and 3?

It's not something that we, as Guix, can do.
The NTP pool is run by a separate organization, and the question of
which DNS names should return AAAA (IPv6) records is open:
https://community.ntppool.org/t/the-time-has-come-we-must-enable-ipv6-entirely/1968
However, the reason they give us 4 different addresses is so that we can
spread the load around. Our NTP services should choose randomly at
run-time. Or we could just make number 2 the default, and then we'll
have IPv6 support. Or something more complicated...

Thanks for the info. I'm now using pool 2 as the default on my IPv6-only
machines, and it works well.
