NAME # lo - software loopback network interface
SYNOPSIS # pseudo-device loop
DESCRIPTION # The loop interface is a software loopback mechanism which may be used for performance analysis, software testing, and/or local communication.
A loop interface can be created at runtime using the ifconfig lo‌N create command or by setting up a hostname.if(5) configuration file for netstart(8). The lo0 interface will always exist and cannot be destroyed using ifconfig(8).

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.

NAME # rtable, rdomain - routing tables and routing domains
DESCRIPTION # The traditional kernel routing system had a single table for routes and allowed only non-conflicting IP address assignments. The rtable feature allows multiple lookup tables for routes. The rdomain feature provides a way to logically segment a router between network paths.
Routing tables # Each rtable contains routes for outbound network packets.
