@paul_ipv6@infosec.exchange The end time of quad9’s NTA is surprising. I realize the can retract whenever, but I vaguely recall RFC specifies a max duration. (BIND: 1 week)

@jpmens@mastodon.social i'll have to check but i think time limit was a SHOULD, not a MUST.

@jpmens@mastodon.social yup. MUST not auto-set or auto-renew but SHOULD allow setting a time limit and that max SHOULD be a week, but no MUST NOT on time limit.
