      DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
           The _p_r_o_t_o_c_o_l_s 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.

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