Description

When running Kea for DHCPv6 on an interface set to track6 against an upstream PD static DHCP leases can be added to unbound before a prefix is available.

This means that leases defined as only the suffix are added to Unbound as only the suffix and hence invalid.

This only happens when Early DNS registration is enabled.

DNS registration should only happen once a prefix has been obtained.

Tested in 25.03-beta.

In addition, static mappings are currently being added without the prefix, even when a prefix is available.
