Internet gateway

An Internet gateway is a key point or address in a local network that enables participants within the network to exchange data with the Internet .

One example is the router from private use. At the level of the IP protocol, the router occupies the IP address e.g. B. 192.168.1.1. All PCs participating in the network send a data request to an IP address that is not in the same network (e.g. 192.168. 2 .37) to the device with the gateway address, i.e. in this case the router, which then forwards the message to the higher-level network or to a neighboring network .
