IP address
An IP address is a numeric label assigned to every device on a network so other devices know where to send traffic. IPv4 addresses are four decimal numbers separated by dots (like 203.0.113.42), drawn from a pool of about 4.3 billion addresses that ran out years ago, which is why ISPs now lean on techniques like CGNAT to stretch what remains. IPv6 addresses are longer hexadecimal strings with a vastly larger address space, designed to give every device its own public address without sharing. Most internet services still see your IPv4 address, your IPv6 address, or both, depending on what your device and network support -- AdminKit's IP lookup shows exactly what the internet sees from your connection right now.
