INET(4) - Device Drivers Manual # INET(4) - Device Drivers Manual
NAME # inet - Internet protocol family
SYNOPSIS # #include <sys/types.h>
#include <netinet/in.h>
DESCRIPTION # The Internet protocol family is a collection of protocols layered atop the Internet Protocol (IP) transport layer, and utilizing the Internet address format. The Internet family provides protocol support for the SOCK_STREAM, SOCK_DGRAM, and SOCK_RAW socket types; the SOCK_RAW interface provides access to the IP protocol.

INET6(4) - Device Drivers Manual # INET6(4) - Device Drivers Manual
NAME # inet6 - Internet protocol version 6 family
SYNOPSIS # #include <sys/types.h>
#include <netinet/in.h>
DESCRIPTION # The Internet Protocol version 6 family is an updated version of the Internet Protocol version 4 family. It comprises Internet Protocol version 6 (IPv6), Internet Control Message Protocol version 6 (ICMPv6), Transmission Control Protocol (TCP), and User Datagram Protocol (UDP). tcp(4) is used to support the SOCK_STREAM abstraction while udp(4) is used to support the SOCK_DGRAM abstraction.

Ip6 IP6(4) - Device Drivers Manual # IP6(4) - Device Drivers Manual
NAME # ip6 - Internet Protocol version 6 (IPv6) network layer
SYNOPSIS # #include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
int
socket(AF_INET6, SOCK_RAW, proto);
DESCRIPTION # The IPv6 network layer is used by the IPv6 protocol family for transporting data. IPv6 packets contain an IPv6 header that is not provided as part of the payload contents when passed to an application.

Netintro NETINTRO(4) - Device Drivers Manual # NETINTRO(4) - Device Drivers Manual
NAME # netintro - introduction to networking facilities
SYNOPSIS # #include <sys/socket.h>
#include <net/route.h>
#include <net/if.h>
DESCRIPTION # This section is a general introduction to the networking facilities available in the system. Documentation in this part of section 4 is broken up into three areas: protocol families (domains), protocols, and network interfaces.
All network protocols are associated with a specific protocol family.

PFLOW(4) - Device Drivers Manual # PFLOW(4) - Device Drivers Manual
NAME # pflow - kernel interface for pflow data export
SYNOPSIS # pseudo-device pflow
DESCRIPTION # The pflow interface is a pseudo-device which exports pflow accounting data from the kernel using udp(4) packets. pflow is compatible with netflow version 5 and IPFIX (10). The data is extracted from the pf(4) state table.
Multiple pflow interfaces can be created at runtime using the ifconfig pflow‌N create command.

Tcpdump TCPDUMP(8) - System Manager’s Manual # TCPDUMP(8) - System Manager’s Manual
NAME # tcpdump - dump traffic on a network
SYNOPSIS # tcpdump [-AadefILlNnOopqStvXx] [-B fildrop] [-c count] [-D direction] [-E [espalg:]espkey] [-F file] [-i interface] [-r file] [-s snaplen] [-T type] [-w file] [-y datalinktype] [expression]

UDP(4) - Device Drivers Manual # UDP(4) - Device Drivers Manual
NAME # udp - Internet User Datagram Protocol
SYNOPSIS # #include <sys/socket.h>
#include <netinet/in.h>
int
socket(AF_INET, SOCK_DGRAM, 0);
int
socket(AF_INET6, SOCK_DGRAM, 0);
DESCRIPTION # UDP is a simple, unreliable datagram protocol which is used to support the SOCK_DGRAM abstraction for the Internet protocol family. UDP sockets are connectionless, and are normally used with the sendto(2) and recvfrom(2) calls, though the connect(2) call may also be used to fix the destination for future packets (in which case the recv(2) or read(2) and send(2) or write(2) system calls may be used).

VXLAN(4) - Device Drivers Manual # VXLAN(4) - Device Drivers Manual
NAME # vxlan - Virtual eXtensible Local Area Network tunnel interface
SYNOPSIS # pseudo-device vxlan
DESCRIPTION # The vxlan pseudo-device provides interfaces for tunnelling or overlaying Ethernet networks on top of IPv4 and IPv6 networks using the Virtual eXtensible Local Area Network (VXLAN) protocol.
VXLAN datagrams consist of an Ethernet payload encapsulated by an 8-byte VXLAN header, which in turn is encapsulated by UDP and IP headers.
