The IPv6 protocol introduced very few changes to its IPv4 predecessor. The major change was of course the expansion of the size of the IP source and destination address fields in the packet header from 32-bits to 128-bits.

This document is not intended to be a comprehensive and detailed technical digest of how to deploy IPv6 in an ISP network that currently has IPv4. Instead it is an executive summary of the 12 fundamental steps, not including services (DNS, web, email, etc.), for native IPv6 support and the maintenance of IPv4 as a transparent service.… Read more
