Convert multiple subdomains into one external IP address.
Convert multiple subdomains into one external IP address.
You're asking about setting up separate subdomains for each server while using one public IP address. It's possible with careful planning, but you'll need to configure DNS properly. You might consider using a DNS service that supports dynamic DNS (DDNS) to keep your IPs updated automatically. Also, ensure your domain hosting is set up correctly with Google Domains or another provider that allows such configurations. If you're comfortable, I can walk you through the steps for setting up DDNS and managing multiple subdomains.
I also think it's important to contribute back. The first one to discover a fix or clarify this impossibility will be the one to share their insight. I can provide you with a valid license for any Microsoft OS you prefer—Windows 10 Pro, Server 2016 Data Center, or other options if you wish. P.S. I've also attached some poorly edited proof.
Generally, they must connect to your public IP address first, then route traffic through ports or use a proxy server. I’m not sure about the Microsoft methods you mentioned, and I don’t know if proxying them that way is feasible—though I do host web servers with external IPs and run Linux applications.
Thank you for the update. Your new business class internet with 13 static IPs should address the problem.
