Link-local addresses are most often unicast network addresses assigned automatically through a process known as stateless address autoconfiguration ( SLAAC) or link-local address autoconfiguration, [1] also known as automatic private IP addressing ( APIPA) or auto-IP.
A router [a] is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. [2] [3] [4] A router is connected to two or more data lines from different IP networks. When a data packet comes in on a line, the router reads the network address information in the packet ...
Virtual IP address. A virtual IP address ( VIP or VIPA) is an IP address that does not correspond to a physical network interface. Uses for VIPs include network address translation (especially, one-to-many NAT ), fault-tolerance, and mobility.
Gateway address. The gateway address (or default gateway) is a router interface connected to the local network that sends packets out of the local network. The gateway has a physical and a logical address.
