IPv6 (Internet Protocol version 6) is a version of the Internet Protocol (IP) intended to succeed IPv4, which is the protocol currently used to direct almost all Internet traffic. For the Internet to make use of the advantages of IPv6 over IPv4, most hosts on the Internet, as well as the networks connecting them, need to deploy this protocol. However, IPv6 deployment has been slow.
The meaning of IPv6 Day is to promote IPv6, in order to accelerate this transition and to motivate private and public companies, Internet providers, application and Internet service creators, and end users to work together on this issue. This year IPv6 day is held on June 6th.
In 2009 Srce joined IPv6 Forum initiative to promote IPv6 and to encourage usage of IPv6. Srce completely adjusted its public web to IPv6 Protocol and was therefore the first institution in Croatia with IPv6 web-enabled certificate.
