    No-ip gives out free dynamic DNS with a static URL. I use it for Sunshine desktop streaming when I travel.

      Yeah, but then you are always exposing your public IP.

        Exposing it to what exactly? The internet? Yes that's how it works

          This requires no port forwarding, so someone brute force scanning your IP won't find this and your open port. they also might have a harder time figuring out what service has been exposed since the port number itself will be unknown.

          If somebody learns that such-and-such DynDNS URL is mine, they can always do a DNS lookup to find my current IP address. They can:

          - find my approximate physical location

          - regularly scan ports on my IP and wait for me to accidentally expose a service I didn't mean to

          - track me in any access logs they have access to

            They can, and do, do this with or without DynDNS.

              Do you mean by getting the information from Cloudflare, or some other way? With DynDNS though, finding out my IP is trivial and does not require any special powers or skills, it is just a DNS lookup.

              PS. Just re-watched your matrix LED pendant video. It is so well done, both the project, and the accompanying video!

                They're scanning all IPs all the time. If your home router has a public IP and a firewall log, check it

                  But with Cloudflare tunnel (and similar tools), there are no open ports on the origin server.
