IPv6 may leave phone web pages reachable from outside

Original: On IPv4, NAT keeps a phone camera page private by accident. On IPv6 there is usually no NAT. A five-minute two-phone tes

A developer is warning that pages served from a phone on an IPv4 network are usually hidden by NAT, but IPv6 assigns globally routable addresses, so the same page can be reachable from outside. The suggestion is a quick two-phone test: try loading the page from another device off the local network to check exposure.

Why now: IPv6 adoption is spreading and people may not realise it removes the accidental privacy of NAT
