German users debate carrier-grade NAT versus real IPv4

Original: Echtes IPv4 und IPv6 am Anschluss – oder nur IPv6 mit geteilter IPv4-Adresse? Das macht einen Unterschied: Portfreigaben

A discussion among German internet users is examining whether home connections still get a genuine public IPv4 and IPv6 address, or only IPv6 with a shared IPv4 address, a setup known as carrier-grade NAT. 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.
