There are several address scopes available. You don't need to use globally unique addresses, if you don't like. This seems to be very common misunderstanding.

- wmf 8y agoNot really. To access the Internet you either need to use global addresses or you need "illegal" NAT66. And consumer ISPs are definitely giving people global IPv6 addresses by default.
- Sami_Lehtinen 8y agoEven if the device has global unique address for accessing Internet, it doesn't mean that you would need to bind the services you're providing to that address. It's totally normal with IPv6 for any device to have multiple addresses, which have different scopes. If you're using privacy addressing you probably have already several addresses in use, then you got the local addresses and you might as well configure ULA for local communication as I've done for services which I don't want to be Internet accessible.
