The new website of the Dutch .nl ccTLD registry does not only provide a fresh new look but also IPv6 connectivity!
:~$ host www.sidn.nl
www.sidn.nl has address 126.96.36.199
www.sidn.nl has IPv6 address 2001:7b8:c05::80:1
Lets hope more registry’s pick up on this and make their site available on IPv6
