Leading internet firms have set 6 June as the World IPv6 launch day.
IPv6 is the new net address system that replaces the current protocol IPv4, which is about to run out of spaces to allocate.
Web companies participating in the event have pledged to enable IPv6 on their main websites from that date.
The Internet Society, which made the announcement, said the day represented “a major milestone” in the deployment of the standard.
Facebook, Google, Microsoft Bing and Yahoo are the inaugural web firms involved.
