FRAMINGHAM, 18 MARCH 2011 - Verisign is the latest major Internet player to sign up for World IPv6 Day, a 24-hour trial of the next-generation Internet Protocol that is scheduled for June 8.
To participate in World IPv6 Day, which is being sponsored by the Internet Society, organizations agree to support IPv6 traffic on their public-facing Web sites. More than 80 Web site operators -- including Facebook, Google, Yahoo and Bing -- have joined the World IPv6 Day trial.
"Verisign is committed to ensuring that the critical Internet infrastructure under our stewardship is fully prepared for rapid, wide-scale IPv6 adoption," said Danny McPherson, Chief Security Officer of Verisign, in a statement.
The goal of World IPv6 Day is for network operators to gather valuable information about how IPv6 functions in production mode and to quantify how many Internet users suffer from IPv6 brokenness, a term that refers to misconfigured or misbehaving gear that will result in some Internet users being unable to access Web sites that operate IPv6. Industry estimates are that 0.05% of Internet users -- or around 1 million Internet users worldwide -- suffer from IPv6 brokenness and likely don't know it.
IPv6 is the long-anticipated upgrade to the Internet's main communications protocol, which is known as IPv4. IPv4 uses 32-bit addresses and can support 4.3 billion devices connected directly to the Internet. IPv6, on the other hand, uses 128-bit addresses and supports a virtually unlimited number of devices -- 2 to the 128th power.
Web sites such as Facebook and Yahoo are upgrading their Web servers, load balancers and software to support IPv6 because the Internet is running out of address space using IPv4.
In February, the Internet Assigned Numbers Authority (IANA) issued the last blocks of unassigned IPv4 addresses to the regional Internet registries, which will dole them out to ISPs and other network operators over the next few months.
Once IPv4 addresses are depleted, Web sites will need to either support IPv6 or use complex mechanisms such as carrier-grade network address translation (NAT) to communicate with IPv6-based users.
Many network vendors are jumping on the World IPv6 Day bandwagon as a way of demonstrating to enterprise customers that their IPv6-based products are ready for prime time. Among the companies that have signed up for World IPv6 Day are Cisco, Juniper, BlueCat Networks and Huawei.
