alt Hacker NewsThe 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.

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

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.
