Dynamic DNS and port forwarding work fine if you really do want to run a server from your residential IPv4 connection. I've done it many times.

Until you run into CGNAT...

  • Sure, but American residential ISPs don't run with that, probably for this reason.

    • I brought up CGNAT because my American ISP does use CGNAT. We are now paying an extra monthly fee for a static IP, which I believe is the only option they have for getting a public IP (i.e. no intermediate fee amount for a public non-static IP).

    • It might be more fair to say that most American residential ISPs don't have to do that because they have access to giant legacy IPv4 allocations. Comcast alone has 65 million IPv4 addresses, for example (including a /8, /9, and /10 and several /11s).
