Questions tagged [ip-address]

An Internet Protocol address (IP address) is a numerical label assigned to each device in a computer network that uses the Internet Protocol for communication. This is a general tag that covers both IPv4 (like 172.168.100.1) and the newer IPv6 (like 2012:da8:0:1234:7:577:8:2). If you specifically mean any of these, use IPv4 or IPv6 tags.
