Good day, IANA is keeping domain registration only as if. WGLC needs this non benefit organization to approve any RFC ? The once recent contacted to for rfc2119 by a domain publisher , there was no replied getting, nor agree with to correct it by ASN co., . From the ALIAS which ASN # assigned to the domain_publisher remaining talked over months yet, tell would care rfc2119 intending to? ISP MAIL srv, lost years msg, downloading msg won't be find where saved due to dhcpv6 srv or network, talked to ofca.gov..., out of tele managing scope as before applying to dhcpv6 bt 2015 ... To RFC wherever not abey-ing the protocols, since "should, must.." words put at RFC, them... Where would force isp, domain publisher ...to follow RFC with monitor from the clients who knowing rules of RFC ?

Based on the discussion it didn't pass WGLC at this time. It will mostly need another round of discussion and potentially a revision based on those discussions. Additionally, Bernie and I discussed and think it's a good idea to wait to ask IANA for a early code points until we have passed WGLC.
