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?
Powerdns and powerdnsadmin works well. Do keep in mind you are assuming responsibility for keeping that server up, if it fails your domains could be impacted (depending on how secondary servers are set up)
