How can I use Dynu.com instead NO-IP, duckDNS, spDYN, freeDNS?

Hello Guys !

your Dynamic DNS setup is really great. Can you please bring another template for Dynu.com or one template in which you can also specify the “server” of the provider as “api.dynu.com” in the case of Dynu.com? That would be great and much more flexible!

Thank you in advance!
