So, while it might be a reasonable design choice to limit the character set to match DNS labels, i.e. US ASCII, that's not technically a requirement. I'm not suggesting doing otherwise, but, it should at least be called out as a conscious decision. Maybe an alternative solution would be "any valid A-label", which would potentially support UTF table entries encoded with puny-code? As for length, as long as it is long enough to encode "bikeshed-colour", I don't really care. :-) Brian > > On Wed, Jul 15, 2020 at 1:07 PM Ólafur Guðmundsson <ola...@cloudflare.com> > wrote: > >> How about 2 or 10 ? >> why do the names to need to be long ? >> >> Olafur >> >> >> On Thu, Jul 9, 2020 at 10:18 PM Erik Nygren <erik+i...@nygren.org> wrote: >> >>> Or 64? >>> >>> >>> >>> - Erik >>> >>> [Sent from my IPv6 connected T-Mobile 4G LTE mobile device] >>> >>> On Thu, Jul 9, 2020, 9:40 PM Ben Schwartz <bemasc= >>> 40google....@dmarc.ietf.org> wrote: >>> >>>> How about 255 characters? >>>> >>>> On Thu, Jul 9, 2020 at 9:25 PM Mark Andrews <ma...@isc.org> wrote: >>>> >>>>> Can we please have a length limit on key names?
