+.SH DESCRIPTION
+This file is a plain ASCII file, describing the various DARPA internet
+protocols that are available from the TCP/IP subsystem.
+It should be
+consulted instead of using the numbers in the ARPA include files, or,
+even worse, just guessing them.
+These numbers will occur in the
+protocol field of any IP header.
+.PP
+Keep this file untouched since changes would result in incorrect IP
+packages.
+Protocol numbers and names are specified by the IANA
+(Internet Assigned Numbers Authority).
+.\" .. by the DDN Network Information Center.
+.PP
+Each line is of the following format:
+.PP
+.RS
+.I protocol number aliases ...
+.RE

+where the fields are delimited by spaces or tabs.
+Empty lines are ignored.
+If a line contains a hash mark (#), the hash mark and the part
+of the line following it are ignored.
+.PP
+The field descriptions are:
+.TP
+.I protocol
+the native name for the protocol.
+For example
+.IR ip ,
+.IR tcp ,
+or
+.IR udp .
+.TP
+.I number
+the official number for this protocol as it will appear within the IP
+header.
+.TP
+.I aliases
+optional aliases for the protocol.
