This document provides an introduction to Internet Protocol version 6 (IPv6). It begins with an abstract describing the objective and scope, which is to explain IPv6 in a simple way for technical and non-technical readers. It then covers key aspects of IPv6 including the 128-bit address format, address types (unicast, multicast, anycast), address scopes (link-local, site-local, global), differences from IPv4, and the need to migrate from IPv4 to IPv6 due to the exhaustion of IPv4 addresses. It also discusses Malaysia's targets for IPv6 adoption and how IPv6 provides improved security over IPv4.
