IPv6 (EN)

IPv6 Architecture

IPv6 is the latest Internet protocol developed as a successor to IPv4 to overcome the limited number of available IPv4 addresses. It uses 128-bit addresses that enable a practically unlimited number of devices on the internet. IPv6 offers not only extended addressing but also improved security features and more efficient packet processing. The migration from IPv4 to IPv6 is an important topic in modern network administration.
