protocols
protocols(4) File Formats protocols(4)NAME
protocols - protocol name database
SYNOPSIS
/etc/inet/protocols
/etc/protocols
DESCRIPTION
The protocols file is a local source of information regarding the known protocols used in the DARPA Internet. The protocols file can be
used in conjunction with or instead of other protocols sources, including the NIS maps ``protcols.byname'' and "protocols.bynumber" and the
NIS+ table ``protocols''. Programs use the getprotobyname(3SOCKET) routine to access this information.
The protocols file has one line for each protocol. The line has the following format:
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.
EXAMPLES

esp 50 ESP # Encap Security Payload for IPv6
ah 51 AH # Authentication Header for IPv6
ipv6-icmp 58 IPv6-ICMP # IPv6 internet control message protocol
