Questions tagged [ip]

IP - Internet Protocol, the most commonly-used set of rules for dispatching data across a large computer network.

IP (Internet Protocol) is a protocol which encapsulates data for transit across the Internet and encodes its source and destination addresses, among other parameters. It implements the network layer (layer 3) of the OSI model.

Questions related to IP (addressing, routing, and protocol issues) fall under this tag; questions merely containing an IP address do not.
