I assume that this means that ipv6 will be supported by 100% of Czech ISPs, but still, Czech citizens are supposed to be able to access Czech government sites even if they are abroad. Many countries don't have much ipv6 adoption yet. Is this even legal?
The judicial branch decide what's legal and what is not in most modern democratic country by interpreting laws written by the legislature. However, in parliamentary systems, like UK or Canada, the government mostly control the legislature and impose its agenda. I'm unsure about Czech republic but clear power separation like the US is uncommon.
You are correct, Czechia is a parliamentary democracy. Usually, the government is formed by the parties that together have a legislative majority in the lesser chamber.
I should clarify that this is not a law, rather a "government decision" (a la "executive order") on how to act on it's law. Forgive me, I'm not well versed in legal English, and the systems are quite different.
It's not wrong though. Besides North America, there are major carriers in India, France who use IPv6-only networks (with 464XLAT), and I know several South American and Asian countries have them as well. In fact, India is a world leader in IPv6 adoption.
Nowadays it's a very common for mobile networks to be IPv6-only because these providers haven't been able to secure large Ipv4 subnets in the early days. Ironically, they have the most devices. However, this is also the reason why phones work much better with XLAT than Windows or Linux.
- The Czech government adopted a new directive titled "The restart of DNSSEC and IPv6 enrollment in the government"
- Until yesterday, no administration on the European continent has made such a decisive step as setting a end-of-support date for IPv4
- Selected date is highly symbolic, the 6th of June, 2032, the 20th anniversary of the World IPv6 day
- This decision has already sparked discussion on the RIPE NCC forums
- "It's a signal to all internet players to take IPv6 seriously"
- Nevertheless, the EU itself has already taken even greater leap towards IPv6 adoption
