World IPv6 Day

The need for the new protocol arises as the older IPv4 runs out of room. “IPv4 has approximately four billion IP addresses (the sequence of numbers assigned to each Internet-connected device),” the Internet Society explains. “The explosion in the number of people, devices and web services on the Internet means that IPv4 is running out of space. IPv6, the next-generation Internet protocol, which provides over four billion times more space, will connect the billions of people not connected today and will help ensure the Internet can continue its current growth rate.”

“The good news is that Internet users don’t need to do anything special to prepare for World IPv6 Day. Our current measurements suggest that the vast majority (99.95%) of users will be unaffected,” says Google network engineer Lorenzo Colitti. “However, in rare cases, users may experience connectivity problems, often due to misconfigured or misbehaving home network devices. Over the coming months we will be working with application developers, operating system vendors and network device manufacturers to further minimize the impact and provide testing tools and advice for users.”
