One reason why IPv6 adoption has been so slow is that everyone is waiting for everyone else to adopt it first. If that’s the reason for your own company’s sluggishness, it’s time to reconsider, because important online partners are already using the network address protocol: Google is leading the way, by offering its services over IPv6.
When you were a kid, all the other kids would head down to the beach, creek, or swimming pool. Even though the purpose was to go swimming, there would be a minute or two before anyone would jump in. Everyone kept waiting for someone else to take that first frigid plunge. It’s the same with businesses getting their feet wet with IPv6. No one wants to be the first to jump in. Well, now you don’t have to, since one of the biggest kids on the block, Google, has already jumped into IPv6.
Google, which saw the need to start moving to IPv6, began its implementation in March 2008. By May of the same year, Google started offering Google Search over IPv6 at http://ipv6.google.com. (Unless you have an IPv6 connection to the Internet this site will not work for you.)
Since then, with Google network engineers Lorenzo Colitti and Erik Kline leading the way, Google has started offering more services over IPv6. It’s not been easy. As Steinar H. Gunderson, a Google open-source and IPv6 developer explained at the Google’s IPv6 Implementers Conference in June 2010, when trying to retro-fit network programs for IPv6 (PDF), your software should “Start listening on IPv6, then send IPv6 data. Watch it crash. Fix, repeat until it looks OK.”
In short, they learned, if you don’t want your company to have real fits come the day that you start implementing IPv6, have your internal programmers start working on in-house software now and start insisting that your ISVs (independent software vendors) deliver IPv6 ready software.
