German users debate carrier-grade NAT versus real IPv4

The difference matters because port forwarding and reaching home services remotely only work reliably with a real IPv4 address. Developers of diagnostic tools are helping users classify their own connection type.

Why now: Growing IPv4 address shortages are pushing internet providers onto shared addresses, breaking home networking features users rely on.
