Is IPV6 Dual-Stack really a best method for IPv6 design ?

There are mainly three IPv6 transition methods; Dual-Stack, Tunnelling and Translation. Careful engineers can understand the difference between IPv6 migration and IPv6 transition.

All of these three technologies are used to bring IPv6 protocol capabilities in addition to IPv4, they are not migration mechanisms. Migration means removing IPv4 completely and running only IPv6 only in the network which might not be the case at least for the next decade.
In this post, I will explain why IPv6 dual-stack unlike most people believe is not the best transition approach.

There is a saying, Dual-stack where you can, tunnel when you must, translate if you have a gun in your head.

IPv6 Design in the Enterprise

ipv6A month ago, I talked with Jeff Doyle about IPv6 Network design in the Enterprise.We strongly advised Enterprise companies to start considering IPv6 deployment.

Below were the subjects.Click here to listen.



  • Why IPv6 in the Enterprise, Real business drivers for the IPv6 in the Enterprise ?
  • Jeff Doyle’s advices to Service Providers
  • IPv6 Addressing Plan
  • IPv6 Design Alternatives for the Enterprises
  1. Starting from Core of the Network
  2. Starting from Edge of the Network
  3. Starting from the Internet Edge
  • Also Jeff Doyle announced that his new book about Software Defined Networking will be published soon. We are planning to talk his new books on the packetpushers podcast and you will be informed from orhanergun.net
