https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270536 Bug ID: 270536 Summary: By default ntpd does not work on IPv6-only hosts Product: Base System Version: 13.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: conf Assignee: bugs@FreeBSD.org Reporter: lapo@lapo.it Default /etc/ntp.conf uses the following server: pool 0.freebsd.pool.ntp.org iburst which does not resolve to any IPv6 addresses: % drill aaaa 0.freebsd.pool.ntp.org ;; ANSWER SECTION: while 2 does: % drill aaaa 2.freebsd.pool.ntp.org ;; ANSWER SECTION: 2.freebsd.pool.ntp.org. 150 IN AAAA 2620:83:8000:ffd1:1::e 2.freebsd.pool.ntp.org. 150 IN AAAA=20=20=20 2601:603:b7f:9731:123:4636:ddb5:5de 2.freebsd.pool.ntp.org. 150 IN AAAA 2604:a880:1:20::8e:3001 2.freebsd.pool.ntp.org. 150 IN AAAA 2620:149:a0c:4000::1f2 I discovered about that on the following thread: https://community.ntppool.org/t/the-time-has-come-we-must-enable-ipv6-entir= ely/1968/44?page=3D3 I'd say it would make sense to either: 1. switch entierly from 0. to 2. in order to support IPv6, but risking prob= lems on server which have IPv6 mis-configured 2. use both 0. and 2. in default ntp.conf, thus guaranteeing both IPv4-only answers and IPv4+IPv6 answers, ntpd will then choose the best/closest one anyways cheers, Lapo --=20 You are receiving this mail because: You are the assignee for the bug.=
