IPv6 introduction

Internet Protocol Version 6 (IPv6), also called IP Next Generation (IPng), is the second-generation standard protocol of network layer protocols. As a set of specifications defined by the Internet Engineering Task Force (IETF), IPv6 is the upgraded version of Internet Protocol Version 4 (IPv4). The main difference between IPv6 and IPv4 is that the IPv6 address is extended from 32 bits to 128 bits. IPv6 is more competitive in future markets with its simplified header, sufficient address space, hierarchical address structure, flexible extension header, and enhanced neighbor discovery mechanism.
Basic functions of IPv6 include IPv6 neighbor discovery and IPv6 path MTU discovery. Neighbor discovery and Path MTU discovery are both implemented through Internet Control Message Protocol for IPv6 (ICMPv6) messages.
