No, there is not. DNS only points to the IP address.
Why You Can’t Include a Port Number with a DDNS IP:
- DNS Standards Limitation: DNS records (like A or AAAA) only map domain names to IP addresses — they do not support port numbers. For example, home.example.com can resolve to 192.168.1.100, but you can’t set it to resolve to 192.168.1.100:8080.
- Port numbers are application-layer concerns: They are interpreted by the client (e.g., browser, app) and not managed by DNS.
