What's the benefit to a traditional consumer application of opening ports these days, besides maybe for local network data exchange (which, I assume, is what Steam does since I know it will sync game updates between machines on the same subnet). I would hazard that the global number of laptops and desktops with public IPv4 addresses in 2024 is probably in the triple digits, given that basically every provider I'm aware of hands off with a "Wi-Fi modem" that converts whatever weird delivery medium (fiber, DSL, cable, etc.), gets its own maybe-public IP, and does NAT for clients. Hell, I don't even have my own IPv4 address since Starlink does CGNAT. |
