      NAME
           protocols - protocol name data base

      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 and/or tab
           characters.  A ``#'' indicates a comment line.

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

      EXAMPLE
           #
           # Internet protocols
           #

           ip   0    IP
           icmp 1    ICMP
           tcp  6    TCP
           udp  17   UDP

      FILES

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