IPv6 Overview
Internet Protocol Version 6 (IPv6), also called IP next generation (IPng), was designed by the Internet
Engineering Task Force (IETF) as the successor to Internet Protocol Version 4 (IPv4). The significant
difference be tween IPv6 and IPv4 is that IPv6 increases the IP address size from 32 bits to 128 bits.
IPv6 Features
Header for mat simplification
IPv6 cuts down some IPv4 header fields or moves them to extension headers to reduce the overhead of
the basic IPv6 header. IPv6 uses a fixed-length header, thus making IPv6 packet handling simple and
improving the forwarding efficiency. Although th
the size of the IPv6 header is only twice that of the IPv4 header (excluding t
specific IPv6 header format, see
