In many of the quotes that Fusix sends out, IPv4 addresses are the biggest cost factor. As anyone reading this article will know, the technology of the successor IPv6 is here, has been proven to work fine and yes, people want it, because in the long run it is cheaper to implement. Let’s start forgetting about the cost of implementing IPv6 and make it the standard!
Marco Hogewoning, External Relations Officer at RIPE NCC and my former colleague, started this discussion and I am on the same page as he is. He argued that instead of looking at the cost of implementing IPv6 and basing our decisions on that, we have to start looking at how much we can save by not having to continue the use of IPv4. And he is right about that.
Right now we are almost out IPv4-addresses. To acquire new ones is possible, but pricy, and it is not going to get cheaper. Yes you can still get IPv4 addresses from the RIPE NCC and there are IPv4 broker companies trading addresses for a fee. But the irony is that at the same time, anyone can get as many IPv6 addresses as they want, all for free!
Companies planning the implementation of IPv6 sometimes claim that investing in IPv6 is not worth the price. They have all kinds of arguments but fail to realize that in the end it will be cheaper to implement IPv6 than to uphold the infrastructure needed to run IPv4 protocols – where not just IPv4 addresses need to be acquired, but also Carrier Grade NAT boxes need to be deployed, both of which cost serious money. “But no one is using IPv6.” Also not true. Today in Belgium, one in two Internet connections has IPv6. And they can stream Netflix as well as we do, and Facebook, Youtube and Microsoft are as reachable as they are in The Netherlands with our IPv4 preference. Our Southern neighbours can teach us in that respect. They are by far the most advanced country in Europe when it comes to implementation of IPv6.
Marco Hogewoning is right (and I can tell you, at the time we worked together, he was usually right, too!). Think of all the money you can save by not having to buy more IPv4 addresses and invest in CGNAT equipment. Forget IPv4, let’s go IPv6!
