In this tutorial, i will demonstrate configuration of IPv6 addressing in both Windows XP machine and Cisco Router (GNS3).One of most flexible migration approach to IPv6 will beĀ  “Dual-stack” approach which means that network devices will have both IPv4 and IPv6 addresses simultaneosly. Both TCP/IPv4 and TCP/IPv6 protocol stacks will work together seamlessly for quite some time.

IPv6 is also called IPng “IP Next Generation”. IPv6 offers exciting new features and addresses needs of today’s robust networking paradigm .

Following are few of many benefits of IPv6 :

  • Larger Address Space:IPv6 features a larger address space than that of IPv4: addresses in IPv6 are 128 bits long versus 32 bits in IPv4
  • Address Scopes :IPv6 introduces the concept of address scopes. An address scope defines the “region” or “span” where an address can be defined as a unique identifier of an interface.
  • Stateless address auto-configuration:IPv6 hosts can configure themselves automatically when connected to a routed IPv6 network using ICMPv6 router discovery messages.
  • Multicast / Multimedia :IPv6 offers built-in features for multicast groups, management and new ” anycast ” groups.
  • Mandatory network layer security :Internet Protocol Secutiry (IPSEC) ,the protocol for IP encryption and authentication, forms an integral part of the base protocol suite in IPv6.
