Document: draft-ietf-v6ops-prefer8781-06 Content: Ready with NITs Reviewer: Sue Review Date: 2025-08-06 IETF LC End Date: 2025-07-28 IESG Telechat date: 2025-08-07 Summary: Ready with NITs: Major issues: none Minor issues: none NITS: 1. section 3.2.2. old text:/ The duration of such period and feasibility of discontinuing DNS64 support, relying solely on RA-based PREF64 signaling in a given network depends on the endpoint footprint, particularly the presence and number of endpoints running outdated operating systems, which do not support [RFC8781]./ Comment: This sentence tries to give advice about the transition period, but the English sentence does not provide a clear recommendation. It is clear that the choices are: 1) when to discontinue DNS65 support 2) how many endpoints are been upgraded to recent OS that supports RFC8781 But is not clear what the recommendation is. -- last-call mailing list -- last-call@xxxxxxxx To unsubscribe send an email to last-call-leave@xxxxxxxx
