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

    aliases

Items are separated by any number of blanks and/or tab characters. A hash (“#”) indicates the beginning of a comment; characters up to the end of the line are not interpreted by routines which search the file.

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