If NAT64 is in use, the device should be identified by its publicAddress and publicPort, or separately by its allocated IPv6 address (field ipv6Address of the Device object) In all cases, publicAddress must be specified, along with at least one of either privateAddress or publicPort, dependent upon which is known.

The developer can choose to provide the below specified device identifiers: * `ipv4Address` * `ipv6Address` * `phoneNumber` * `networkAccessIdentifier` NOTE1: the MNO might support only a subset of these options. The API invoker can provide multiple identifiers to be compatible across different MNOs. In this case the identifiers MUST belong to the same device NOTE2: for the Commonalities release v0.4, we are enforcing that the networkAccessIdentifier is only part of the schema for future-proofing, and CAMARA does not currently allow its use. After the CAMARA meta-release work is concluded and the relevant issues are resolved, its use will need to be explicitly documented in the guidelines.
