Running IPv6 Only Networks

from Underlay | Published 1/5/2021

In today’s episode we’re talking about IPv6. More specifically, we discuss what it takes to run an IPv6 only network. Why now? And why not dual stack? Well, in the middle of November (2019), the US government put out a memo outlining their updated guidelines and expectations for IPv6. In it, they mandate a future vision of 80% of devices connected to IPv6 only networks by 2025. That’s not that far away. So, as many of our peers who work in US federal organizations are preparing for a world that is IPv6 only, we figured it might be time for us to do the same.  Show Notes Impact of OMB memo (is this the same as last time or not?)

This memo mandates IPv6 only network adoption. What are some of the additional considerations that need to be considered when jumping straight from IPv4 to IPv6.  What is the current state of IPv6 networking hardware today?  Data Plane Management Plane Orchestration? What are some of the biggest hurdles to adopting IPv6 exclusive networks, as compared to a dual-stack approach? Other challenges of IPv6-only Disabling IPv4-stack on hosts, how to signal to them that this is an IPv6-only access network   Thank you to BlueCat Networks for sponsoring today’s episode.
