What do you mean by popular? I hosted a site on a home machine in the early teens. If you don't know how to do that with NAT, you should not have a web server under your control exposed to the internet.

The early teens didn’t have huge proliferation of ISPs using CGNATs.

These days ISP can’t get hold of new IPv4 blocks, and increasingly don’t provide public IP addresses to residential routers, not without having to pay extra for that lowly single IPv4 address.

Hosting a website behind a NAT isn’t as trivial as it used to be, and for many it’s now impossible without IPv6.

    The example I keep coming back to is multiplayer games like Mario Kart, where Nintendo tell you to put the Switch in the DMZ or forward a huge range of ports (1024-65535!) to it [1].

    If you’ve got more than one Switch in the household, though, then I guess it sucks to be you.

      To require that, the person would have needed to disable upnp on their router. I’ve played tons of multiplayer games on the switch and upnp handled it seamlessly on the 7 or 8 home networks I connected it to over its life. Never once even had to think about it.

      So yes, if you disable the requisite, standard, built-in feature on your router, you may need a pretty annoying workaround. Weird!

      What percentage of users do you imagine disable upnp? Let’s be real. This is a problem that your average user will never, ever experience a problem with.

    It's impossible with ipv6 either. ISPs block incoming connections on ipv6 for residential addresses.
