23.7 Legacy Series / Re: IPV6 Interface Addresses

Guessable interface addresses shouldn't be a concern, a security strategy should never depend on keeping IP addresses "secret".
Privacy extensions are not commonly used on routers, only on hosts. The interface identifiers are based on the MAC address (EUI-64). If all VLANs use the same underlying NIC, they share the same MAC address and as a result the same interface identifier. You can spoof the MAC address for individual VLANs though.
