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:
* the AAAA entry points to the server directly
* the A entry points to a proxy
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.
This is our first tech talk and we love to [hear your feedback](/u/contact/).
