You should write to the people that did the commits and ask them.

I must have misread.  The iana link above clearly has submissions =
465/tcp.  It also has urd.  So our file should of course match.


There's a huge point here that I want to make explicit.  We need to have
a sane process for updating from IANA, and that involves

  - having a script to convert IANA into our format

  - having that script checked into the sources

  - some mechanism to maintain the "local additions" section at the end

  - probably a scheme to maintain any diffs from IANA, if we really want
    any

  - probably a way to build a new file from iana-converted and local
