ADDRESS_FAMILIES(7) Linux Programmer's Manual ADDRESS_FAMILIES(7) NAME address_families - socket address families (domains) SYNOPSIS #include <sys/types.h> /* See NOTES */ #include <sys/socket.h> int socket(int domain, int type, int protocol); DESCRIPTION The domain argument of the socket(2) specifies a communication domain; this selects the protocol family which will be used for communication. These families are defined in <sys/socket.h>. The formats currently understood by the Linux kernel include: AF_UNIX, AF_LOCAL Local communication For further information, see unix(7). AF_INET IPv4 Internet protocols. For further information, see ip(7). AF_AX25 Amateur radio AX.25 protocol. For further information, see ax25(4). AF_IPX IPX - Novell protocols. AF_APPLETALK AppleTalk For further information, see ddp(7). AF_NETROM AX.25 packet layer protocol. For further information, see netrom(4), The Packet Radio Protocols and Linux <https://www.tldp.org/HOWTO/AX25-HOWTO/x61.html> and the AX.25, NET/ROM, and ROSE network programming chapters of the Linux Amateur Radio AX.25 HOWTO <https://www.tldp.org/HOWTO/AX25-HOWTO/x2107.html>. AF_BRIDGE Can't be used for creating sockets; mostly used for bridge links in rtnetlink(7) protocol commands. AF_ATMPVC Access to raw ATM Permanent Virtual Circuits (PVCs). For further information, see the ATM on Linux HOWTO <https://www.tldp.org/HOWTO/text/ATM-Linux-HOWTO>. AF_X25 ITU-T X.25 / ISO-8208 protocol. For further information, see x25(7).

AF_IRDA Socket interface over IrDA (moved to staging in Linux 4.14, removed in Linux 4.17). For further information see irda(7). AF_PPPOX Generic PPP transport layer, for setting up L2 tunnels (L2TP and PPPoE). See Docu- mentation/networking/l2tp.txt in the Linux kernel source tree for details. AF_WANPIPE Legacy protocol for wide area network (WAN) connectivity that was used by Sangoma WAN cards (called "WANPIPE"); removed in Linux 2.6.21. AF_LLC Logical link control (IEEE 802.2 LLC) protocol, upper part of data link layer of ISO/OSI networking protocol stack (since Linux 2.4); has no relation to AF_PACKET. See chapter 13.5.3.

See also some historical notes <https://wiki.linuxfoundation.org/networking/llc> regarding its development. AF_IB InfiniBand native addressing (since Linux 3.11). AF_MPLS Multiprotocol Label Switching (since Linux 4.1); mostly used for configuring MPLS routing via netlink(7), as it doesn't expose ability to create sockets to user space. AF_CAN Controller Area Network automotive bus protocol (since Linux 2.6.25). See Documen- tation/networking/can.rst in the Linux kernel source tree for details. AF_TIPC TIPC, "cluster domain sockets" protocol (since Linux 2.6.16).
