This is the source of the PowerDNS pipe backend adapter powering polisystems.cloud.
Install this on your system, adjust etc/xip-pdns.conf to your liking, and configure PowerDNS as follows:
launch=pipe
pipe-command=/path/to/xip-pdns/bin/xip-pdns
We resolve the URL's to the ip's using a PowerDNS backend 1.2.3.4.polisystems.cloud -> 1.2.3.4
