Just as a quick note here:
I originally planned to do my third part on DNSSEC with configuration hints using the popular DNS server BIND. At the moment I also use BIND for my setup.
Now I discovered the „Advanced Secuity Notifications“ at ISC, which sells prior warnings about security issues in BIND. Personally, I don’t want to support this model.
Instead I am currently migrating to another DNS server implemenation, YADIFA, which I will then write about. But first I need to check my setup using this server.
Update: Maybe I will switch to Knot DNS instead of YADIFA. They seem to be both fairly equal in features. To the outside spectator YADIFA seems to be a dead project, even though they published a release in mid-december. The development is done by EUnic, the guys behind maintaining the .eu-domain. They seem to have some internal development/issue tracking/etc. and they only send the releases to GitHub.
In contrast, Knot DNS, being maintained by cz.nic, is more open in their development.
