As Duck DNS is a bit inconsistent recently, where sometime your domain will get resolved with the previous public IP!, I wanted to rely on multiple DDNS at the same time, while still having single SSL certificate for them for a secure access.

Thanks to @koying provided a great addons using Dynu DNS. However, it won’t be possible to use DuckDNS at the same time.

I decided to put some efforts to build a modified version of Dynu DNS that can create a single certificate for multiple DDNS domains from either DuckDNS or Dynu DNS.

Multi-DDNS Add-on

I was looking for dynu support for Let’s Encrypt and found this. How does this work with Let’s Encrypt without dynu being a supported dns provider in LE?
