IPv6 World Day is an unexpected success in the Czech Republic
Prague, 13 June 2011 – IPv6 World Day attracted a great deal of interest by many companies in the Czech Republic. According to the statistics of the CZ.NIC Association, the administrator of the Czech national domain, on 8 June, one in ten .cz domains was accessible over IPv6. The NIX.CZ national switching centre also noted an increase in IPv6 flows over seven times the normal level. IPv6 World Day was created on the initiative of companies such as Google, Yahoo and Facebook, with hundreds of organisations participating worldwide. The Czech Republic is the world leader in introducing IPv6, as was confirmed on this international day.
“According to our statistics, on 8 June the number of .cz domains accessible over IPv6 increased by almost 30 percent, which means that over 18,000 websites in the Czech domain space turned on their IPv6 support on that day. On Wednesday, the number of Czech domain sites accessible over IPv6 was over 81,000 (out of the 808,000 total sites). The interest and participation of many companies in this event are commendable. Many saw this as an opportunity to test preparations for the final switch to IPv6,” said Ondřej Filip, Executive Director of the CZ.NIC Association.
The Czech switching centre, NIX.CZ, also noted a significant increase in the use of IPv6.
“IPv6 data flows in the national switching centre on 8 June increased sevenfold, to over 1 Gbps. This confirms that many companies took IPv6 World Day seriously,” added Martin Semrád, Executive Director of the NIX.CZ Association.
The CZ.NIC and NIX.CZ Associations jointly organised a conference called Internet and Technology 11 on 8 and 9 June. The first day of the event focused exclusively on issues related to IPv6. Presentations, videos and a recording of the panel discussion with representatives of the largest internet service providers and internet content providers in the Czech Republic will be published at www.nic.cz/it11 in early July.
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.
