Hi! Still I guess with a REFID as extension field could provide a solution "sooner" as NTPv5, and it could be available in selected NTPv4 servers in the near future. > > The "MAC/last extension field" draft would be obsolete if we define that > NTPv5 does only support Extension Fields as allowed additional data and a MAC > in v5 is always transported inside an extension field (the "MAC-EF" approach > as described in the draft, for example). Just a random thought: Would it make sense for NTPv5 to create a completely new packet format, or should NTPv5 be based on extension fields? Some old clients could still try to interpret a new format with old rules (inoring the version number). With extension fields the old clients could use NTPv5 "somewhat" (ignoring all true v5 additions), while with a new format those clients will have a problem.
