At ungleich we have a lot of IPv6-only web servers. Many of them are
|
|
|
|
|
are proxied from the IPv4 world, so the domain name points to two
|
|
|
|
|
different machines:

This sometimes makes configuring the right system a bit harder,
|
|
|
|
|
because on dual stack clients, accessing www.example.com brings you to
|
|
|
|
|
either machine. In the [first ungleich tech
|
|
|
|
|
talk](https://www.youtube.com/watch?v=cANwo0IdZYU) we show how this
|
|
|
|
|
looks in detail and how we ensure that we configure the right machine.
