But I am still confused which software to use. I was greatly leaning towards PowerDNS until I saw that PowerDNS is going messy when it comes to deleting zones on slave servers. It does not do that! And to do that, we’ll have to run scripts on slave servers through cron.
Now, I am leaning towards BIND but none of the documentation is clear enough to give me an idea of how to setup MASTER-SLAVE configuration correectly. It will not just be used for 1 domain but about 10000 zones or even more…
Do you guys have any suggestions of which open source DNS servers to use or which way I should go?
UPDATE: It will be a free service for my customers… That’s why It’s architecture should be scalable!
