How an IP address works

How an IP address works

192.168.1.42 is 32 switches.

Each of the four numbers is eight bits, on or off. On a typical home network the first three numbers name the network, like a street, and the last one names your device, like a house.

32 bits only make 4,294,967,296 addresses. That ran out, so IPv6 uses 128 bits.
