Internet Protocol version 6 (IPv6) is the next generation of Internet Protocol and is gradually replacing the current Internet standard, Internet Protocol version 4 (IPv4). The key IPv6 enhancement is the expansion of the IP address space from 32 bits to 128 bits, providing virtually unlimited, unique IP addresses.
IPv6 provides several advantages over IPv4, including expanded routing and addressing, routing simplification, header format simplification, improved traffic control, autoconfiguration, and security.
