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

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

  • 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

  • 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.
