Just a note (this recently came up on the ntp-pool list):

Only 2.$ntppooldomain subdomain has AAAA records.

root at hellhound ~ # host 2.pool.ntp.org
2.pool.ntp.org has address 190.66.14.207
2.pool.ntp.org has address 72.26.198.240
2.pool.ntp.org has address 84.2.44.19
2.pool.ntp.org has address 173.248.162.90
2.pool.ntp.org has IPv6 address 2607:f0d0:2001:de::add
2.pool.ntp.org has IPv6 address 2001:1900:201e:6:6e62:6dff:fee5:821
2.pool.ntp.org has IPv6 address 2001:4f8:fff7:1::17
2.pool.ntp.org has IPv6 address 2600:3c00::f03c:91ff:fedf:ddfe

root at hellhound ~ # host 1.pool.ntp.org
1.pool.ntp.org has address 205.233.73.201
1.pool.ntp.org has address 208.88.126.226
1.pool.ntp.org has address 38.101.77.21
1.pool.ntp.org has address 173.244.211.10

root at hellhound ~ # host 3.pool.ntp.org
3.pool.ntp.org has address 72.8.140.200
3.pool.ntp.org has address 199.102.46.72
3.pool.ntp.org has address 108.61.73.244
3.pool.ntp.org has address 71.41.45.68

So if you are in an IPv6 only environment, make sure the ntp pool FQDN
you are using has AAAA records.
