Talking here RFC... would be configured , developed at server where when ISP dhcpv6 runner, won't care the RFC... , a client asked telecommunication Ltd, where think only ordinary, contractor under scope, RFC as to be protocol where can audit ISP for its loose managing to RFC...? That talking can go to realize in practice? RFC since 2119, 3315 started by 2015 talked to: ISP Ofca.gov.hk Ietf.org Domain publisher ... no where truly according to these RFC very sould reasonable policy , protocol what best call the RFC, to abey them in server, at ISP, domain issuer etc. unsure ? For home user, yet at ware, vw to develope with these RFC .., When met IoT relating to RFC... tried to remind isp, domain where facing to like no matter for them always?
