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 Cloudflare. I just have the users add the Cloudflare nameservers to their domain. Once all is done, I can make DNS changes while the customer continues to pay for the domain using their preferred registrar.
