Default Gateways

Networking Topics > Layer 3 Routing > Default Gateways

A Default gateway is the IP address of the interface, or port, of the router which is attached to the local segment. The local segment being the network to which the host is located.

All hosts on the local segment must have a default gateway set to the IP address of the interface of the router that is attached to this local segment.

Without the default gateway being set on a host, communicating with hosts on networks other than the local segment would be impossible.
