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, includ‐
       ing the NIS maps ``protcols.byname'' and "protocols.bynumber"  and  the
       NIS+ table ``protocols''. Programs use the getprotobyname(3SOCKET) rou‐
       tine 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. Proto‐
       col names may contain any printable character other than a field delim‐
       iter, <NEWLINE>, or comment character.

EXAMPLES
       Example 1: A Sample Database

       The following is a sample database:

       #
       # Internet (IP) protocols
       #
       ip	   0   IP	   # internet protocol, pseudo protocol number
       icmp	   1   ICMP	   # internet control message protocol
       ggp	   3   GGP	   # gateway-gateway protocol
       tcp	   6   TCP	   # transmission control protocol
       egp	   8   EGP	   # exterior gateway protocol
       pup	   12  PUP	   # PARC universal packet protocol
       udp	   17  UDP	   # user datagram protocol

       #
       # Internet (IPv6) extension headers
       #
       hopopt	   0   HOPOPT	   # Hop-by-hop options for IPv6
       ipv6	   41  IPv6	   # IPv6 in IP encapsulation
       ipv6-route  43  IPv6-Route  # Routing header for IPv6
       ipv6-frag   44  IPv6-Frag   # Fragment header for IPv6
       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
       ipv6-nonxt  59  IPv6-NoNxt  # No next header extension header for IPv6
       ipv6-opts   60  IPv6-Opts   # Destination Options for IPv6

FILES
       /etc/nsswitch.conf      configuration file for name-service switch
