alt Hacker NewsWhat's a "white IP address"? It is, sadly, more difficult than it should be, though. When everyone got online in the 90s they actually became bottom feeders and not true internet citizens. Not much has changed in 30 years. IPv6 is necessary, but the world also sucks now so people need to know what they're doing with firewalls etc. Domains are not too bad now, there are some decent registrars now like Porkbun.
"white IP address" is an address that your internet provider gives you and which is accessible from the whole internet, not just some address local for the provider's network and hidden behind NAT. Since IPv4 addresses are scarce, most providers don't allocate them directly to their customers.
An unique IPv6 may be theoretically assigned to each end device and thus solve the accessibility problem for locally-hosted servers, but I doubt internet providers do this in practice and I am afraid that many providers don't support IPv6 at all.
