The North American IPv6 Task Force (NAv6TF) 2017 conference is to be held at LinkedIn’s headquarters (Sunnyvale, CA) on the 26th and 27th April 2017. Details can be found here.

Erion’s chief consultancy and CEO Dr. David Holder will be speaking at the event on  CGN a Driver for IPv6 Adoption. Here is the abstract:


The IPv4 address space is exhausted and the scarcity of addresses is leading to the deployment of techniques to preserve and better utilise currently allocated addresses. Amongst these techniques, Carrier Grade NAT (CGN) is one which service providers are increasingly deploying in their access networks.

The long-term solution to address exhaustion is IPv6 with its enormous address space. However, the existing and widespread deployment of IPv4 networks and systems make it necessary to continue to support IPv4 into the near future.

The deployment of CGN is not without its challenges. CGN in the data path affects all players; end users, application developers, service providers, carriers and content providers. CGNs can impact banking applications, internet advertising, internet analytics, legal Intercept, computer forensics, privacy, voice and messaging applications, games consoles applications, AJAX applications and much more.

This presentation reviews the implications of CGN, how it affects all parties, the actions that can mitigate CGN issues and why the increasing deployment of CGN is an important driver for the adoption of IPv6
