So I have 100+ websites I manage for various clients, and it is a pain for me to login to their hosting or domain registrar accounts to manage their DNS.
Is there a simple solution, where I can turn on my own server that manages DNS? So for every domain I manage, I simply set a DNS once as ns1…com, and from thereon I can just manage their DNS configurations?
I use Technitium DNS for all my DHCP/DNS/Ad Blocking.

I tired it with about 400 domains and so far it is looking good but it needs a lot more work; someone will have to write a serious command line tool as we all know that GUI tools are good for a few clicks here and there but serious work needs a terminal.
