Yes, that’s correct. According to the IPv6 protocol, when a device is assigned an IPv6 address for the first time, it must be a link-local address. A link-local address is used for communication within the local network segment and cannot be used for communication outside of that segment. It is automatically generated by the device using its MAC address or randomly if no MAC address is available. Once the device has obtained a link-local address, it can then proceed to acquire global or unique local addresses through various mechanisms such as stateless autoconfiguration or DHCPv6.
