The .CZ domain is the leader in content available over IPv6
Prague, 7 June 2011 – Tomorrow is World IPv6 Day, and many leading global content providers will open their servers to this new protocol. In the case of many servers operating under the .CZ domain, this day will be no experiment, but simply business as usual. According to statistics from the CZ.NIC Association, nearly 8 % of the content on .CZ addresses is already available over the IPv6 protocol. This figure has grown more than fivefold over the past 12 months. At the same time, the share of content available over IPv6 on the largest domains at the highest level such as .com, .net and .de is only around one percent.
“The IPv6 issue is one of our top priorities; over the past two years in particular we have tried hard to draw attention to IPv6 and support its introduction. If this trend continues, the .CZ domain will be one of the best prepared when IPv4 is definitively exhausted, which is anticipated to occur here in Europe sometime around the end of 2011 and the beginning of 2012,” says Ondřej Filip, executive director of the CZ.NIC Association and the person responsible for administration of the .CZ domain. “We should commend service providers and Internet users in the Czech Republic for preparing in advance for the transition to IPv6 and not waiting until the last minute.”
On the occasion of tomorrow’s World IPv6 Day, the CZ.NIC Association has also prepared its annual Internet and Technology Conference, the first day of which will be devoted exclusively to the IPv6 issue. The conference is set to begin at the Lávka Club in Prague at 10 a.m. Those unable to attend in person can follow the program online at https://www.nic.cz/it11/. One of the most interesting features of the conference will be a panel discussion with representatives from leading Internet connection and content providers – Telefónica O2, UPC, MAFRA, Seznam.cz and Centrum Holdings.
“Connection providers will play a critical role in the entire transition to IPv6, as they must make relatively demanding and time consuming infrastructure modifications,” added Ondřej Filip.
IPv4 and IPv6
IP addresses are the building blocks of the internet, as without them, computers could not connect to the global network. The IPv4 protocol version was created as early as the 1970s and offered capacity for connecting fewer than 4 billion computers. A solution to the rapidly diminishing stock of IP addresses of version 4 has been around for several years. It is a new version of the internet protocol – IPv6. It provides what seems to be an inexhaustible stock of new addresses (2^128, which is roughly 1 and 38 zeros), but is still not commonly used.
For providers of internet services, the switch to IPv6 primarily means investing in IPv6-compatible technologies. The volume of investment will depend on how much infrastructure the respective entity has. For end users of the internet, the switch to the new protocol may require the purchase of a new modem that supports IPv6. Such devices usually cost between CZK 1,000 and CZK 2,000.
