The zone already exists on the internet so, logically, FreeIPA wouldn't allow me to hijack this domain locally. My usecase is special, so I wanted to forcefully add this zone as a forward zone.

I had only setup my smokepings for IPv4. Recently we had an issue were network config was borked and the whole IPv4 network was not announced via BGP anymore. I was at home troubleshooting, but finding nothing since I have native IPv6 and that part still worked. My Smokeping did show loss, and that explicitly uses IPv4. That helped with the debugging a lot. I have a [IPv4][4] version of this article as well.

This way you can build your smokeping config faster. Sat, 28 Jun 2014 00:00:00 GMT Sat, 28 Jun 2014 00:00:00 GMT
