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 between IPv6 and IPv4 is that IPv6 increases the IP address size from 32 bits to 128 bits.

Header format simplification
IPv6 cuts down some IPv4 header fields or move them to the IPv6 extension headers to reduce the
length of the basic IPv6 header. IPv6 uses the basic header with a fixed length, thus making IPv6
packet handling simple and improving the forwarding efficiency. Although the IPv6 address size is four
