The gateway is on the same network as end devices. The gateway address must have the same subnet mask as host devices. Each host on the network uses the same gateway. The gateway should have a static address, as changing the address would cause packets not to be delivered. The gateway is typically assigned either the highest or lowest network ...
A residential gateway is a small consumer-grade gateway which bridges network access between connected local area network (LAN) hosts to a wide area network (WAN) (such as the Internet) via a modem, or directly connects to a WAN (as in EttH), while routing. The WAN is a larger computer network, generally operated by an Internet service provider.
The default gateway can be specified by the route command to configure the node's routing table and default route. In a home or small office environment, the default gateway is a device, such as a DSL router or cable router, that connects the local network to the Internet. It serves as the default gateway for all network devices.

I2P is fully distributed and works by encrypting all communications in various layers and relaying them through a network of routers run by volunteers in various locations.
