The Business Parallels between IPv6 and DNSSEC

 For two things that would seem to be completely unrelated there is an interesting parallel between IPv6 and DNSSEC.  In both cases there is a misalignment of interests between content providers and service?providers.   Content providers aren’t highly motivated to deploy IPv6 because only a small proportion of users have v6 connectivity and even fewer only have v6.  Service providers aren’t anxious to deploy IPv6? because there isn’t a lot of content on v6, and virtually none exclusively on v6 – so they don’t expand the universe of interesting stuff on the web by deploying IPv6.  Basically the same things could be said about DNSSEC.  Content providers don’t sign their domains so there is little reason to validate; and no one is validating so there is little reason to sign, at least until recently.  Fortunately this is starting to change on both fronts.

A logical place to start the IPv6 transition

The transition to IPv6 is top of mind for most service providers. Even in places where there are still IPv4 addresses to be had surveys we’ve run suggest v6 is solidly on the priority list.  That’s not to say everyone has the same strategy.  Depending where you are in the world transition options are different – in places such as APAC where exhaustion is at hand one of the many NAT alternatives will likely be deployed since getting a significant allocation of addresses is not going to happen and other alternatives for obtaining addresses will prove expensive.  Ditto the European region, who is next on the list to find the IPv4 shelves bare.

With IPv6 World Launch coming up it’s worth pausing to consider the collective efforts of the Internet industry in enabling and deploying an essential evolutionary technology at what will become truly massive scale. It’s easy to be a detractor and believe there has been little progress – but the Internet hasn’t melted down and there is no evidence it is about to.  Perhaps the issue is that progress occurred in a different way than was predicted or preferred by the experts.  The reality is providers everywhere have developed coping mechanisms for IPv4 exhaustion.  Innovation, operational sweat, and perhaps some tough negotiating make it happen.  But isn’t that the essence of the Internet?

Ready for IPv6?

Service providers everywhere are executing on IPv6 transition strategies, some with more urgency than others. Numerous approaches to enable the transition are being implemented, with a goal of maximizing the utility of IPv4 addresses while ensuring 100% connectivity to the small but rapidly growing base of IPv6 addressed hosts. Regardless of technologies being deployed it’s important not to overlook the DNS since new stresses will be placed on it during the transition. Since every service provider has allocated budget for IPv6 readiness, now’s a great time to ensure the DNS is really “ready”. A couple of simple steps will ensure customers continue to enjoy fast response times and high service levels.
