In this post and others my aim is to provide some engineers with a brief but useful …

IPv6 Tutorial

This is a collected IPv6 tutorial form IPv6 posts we have written and should be a good starting point for anyone who is just learning about IPv6.

It simplifies aspects of address assignment (stateless address autoconfiguration), network renumbering, and router announcements when changing network connectivity providers. It simplifies processing of packets in routers by placing the responsibility for packet fragmentation into the end points. IPv6 overview IPv6 is also called IPng or IP next generation; it builds on …
