NAME
     protocols - protocol name database

DESCRIPTION
     The protocols file contains information regarding the  known
     protocols  used  in the DARPA Internet.  For each protocol a
     single  line  should   be   present   with   the   following
     information:

          official protocol name
          protocol number
          aliases

     Items  are  separated  by  any  number  of  blanks  or   tab
     characters.   A  #  indicates  the  beginning  of a comment;
     characters up to the end of the line are not interpreted  by
     routines that search the file.

     Protocol names may contain  any  printable  character  other
     than a field delimiter, newline, or comment character.

LIMITATIONS
     A name server should be used instead of a  static  file.   A
     binary  indexed  file  format  should  be available for fast
     access.
