PROTOCOLS(5)
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 and/or tab characters. A “#” 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.
NOTES
A name server should be used instead of a static file. A binary indexed file format should be available for fast access.
