A panel of network engineers from Comcast, APNIC, T-Mobile, and Facebook discuss the performance benefits and practicalities of deploying IPv6-only networks.

Speakers: John Jason Brzozowski, Comcast Geoff Huston, APNIC. Gaurav Madan, T-Mobile USA Inc. Paul Saab Use of IPv6 is gaining momentum. For some companies it is the primary IP version of choice to run their businesses and to deliver products and services to their customers. The depletion of globally routable IPv4 and private IPv4 address space has prompted many technology firms to look at the use of IPv6 while abandoning support for IPv4 in some parts of their networks. Additionally, and perhaps, more interestingly IPv6 has been rumored to outperform IPv4. New data is available from more diverse adopters that further substantiates these claims. Come hear the following as part of this panel: * Facebook will share information about their IPv6 only efforts including the data they are seeing comparing IPv4 and IPv6 performance. * Comcast will share how they are using IPv6 only for their next generating entertainment operating system as well as IPv6 differences compared to IPv4. * T-Mobile will share information about the deployment of IPv6 only across their mobile network which minimally includes lessons learned and techniques to ensure IPv4 content continues to be reachable. Other participants may be added in advance of the actual panel session. Akamai and LinkedIn have both been invited. - See more at: nanog.org/meetings/nanog64/agenda#sthash.Dz9Xz6Qx.dpuf

What people say. Recommended for its real-world data showing that IPv6 can outperform IPv4 and for insights into large-scale IPv6-only deployments.

Comcast is going for a pure IPv6 core network, they are currently at 60% of their customers getting an IPv6 address of some sort (cable modem or even cable box). T-Mobile's network is IPv6 as well. Especially for customer devices that support 464XLAT: link There is a LOT of support for IPv6, and many companies like Facebook are finding that IPv6 actually offers better performance end to end for their users. Take a look at this NANOG presentation: link to this video

On “IPv4 Depletion”

…1 2) The residential ISPs will debundle the IPv4 from the cost - given that a lot of the sites average consumer needs (google, facebook, youtube, netflix) are already IPv6-enabled. For this case, you will not be even able to see that something is "wrong". Just the users will click on the link, see it's not reachable, say "huh?" and move on. 1 link to this video - 1h12 well spent.…

NATs do induce a fair amount of latency. It's not exaggerated. Watch Paul Saab from Facebook talk about how much better IPv6 performs at NANOG 64: link to this video

On “Comcast Automatically Enabling IPv6 in San Francisco”

An engineer at Comcast in this nanog video 1 claims they have 60% penetration in their own network for IPv6. Which is excellent news. 1: link to this video

…and the usefulness of this IP will slowly fade. There's no panic. The trick with IPv6 deployment is predicting two years in advance the moment will you need IPv6 "tomorrow" - because for a lot of orgs that's how long it takes. I'll repost a link from the recent NANOG meeting here about the folks seriously discussing their plans of going IPv6-only: link to this video By the way, if you're reading this from a smartphone in the US, try this link: link I thoroughly enjoyed the moment when one networking pro (who dealt with IPv6 20 years ago and not since) was telling me he won't have IPv6 till he retires, realized he had his on his LTE connection and was using it for quite some time already! :-) I repeat…

That's simply not true. Over 22% of US Internet consumers have IPv6 addresses. Your mobile phone probably has a (few) IPv6 addresses. From NANOG 64: link to this video

In addition to other answers, here is some food for thought: Some operators are already working on turning IPv4 off in their networks: link to this video

This is contrarian to real world testing: link link to this video Facebook and many other companies are finding that IPv6 is faster, personally at home I have found that disabling IPv4 allows me to more quickly buffer and stream Netflix, and about 30 - 40% of my traffic is IPv6. My Apple TV is the last hold-out that still seems to use IPv4 over IPv6 for Netflix.
