            Bug ID: 295739
           Summary: /etc/protocols missing a few protocols
           Product: Base System
           Version: Unspecified
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: conf
          Assignee: bugs@FreeBSD.org
          Reporter: chris@officialunix.com

if you compare /etc/protocols to the one found at:
https://www.iana.org/assignments/protocol-numbers/protocol-numbers.txt

some have been deprecated such as 122 (SM)

the +#      138-254                 # Unassigned
is invalid as according to IANA 138-254 are used:

So i think this file should be updated to suite but I do not know the syntax to
be used?

that should be changed to 148-252 Unassigned or Not used.
