This website is now served via IPv6 in dualstackmode. Furthermore it is now possible to use the IP service via IPv6.
As of writing this it is possible to use HTTPS for the subdomain ip.philipp-koch.net. For compatibility reasons an automatic redirect from HTTP to HTTPS isn't set up, nether isn't HSTS or HPKP.
Today marks the launch of the new design and structure of this site. In the future the site will be filled with more information.
