I just purchased dyn pro account and succeeded connecting xxx.dyndns.org into my home server.
The next step I want to do is connecting my domain in dyn's name server, so visitors can access here via my domain.
My domain is registered in GoDaddy now.
I tried to search documentation, but I couldn't see anything in my zone: https://account.dyn.com/services/zones/
Did I miss something or did I purchased a wrong service?
You could create a CNAME record for your domain, pointing at your Dyn hostname. There is no other Dynamic DNS service beside DynDNS Pro anymore. You may have bought the wrong service.
