* 16.10 Who-Is and I-Am Services <br>
* The Who-Is service is used by a sending BACnet-user to determine the device
* object identifier, the network address, or both, of other BACnet devices
* that share the same internetwork.
* The Who-Is service is an unconfirmed service. The Who-Is service may be used
* to determine the device object identifier and network addresses of all devices
* on the network, or to determine the network address of a specific device whose
* device object identifier is known, but whose address is not. <br>
* The I-Am service is also an unconfirmed service. The I-Am service is used to
* respond to Who-Is service requests. However, the I-Am service request may be
* issued at any time. It does not need to be preceded by the receipt of a
* Who-Is service request. In particular, a device may wish to broadcast an I-Am
* service request when it powers up. The network address is derived either
* from the MAC address associated with the I-Am service request, if the device
* issuing the request is on the local network, or from the NPCI if the device
* is on a remote network.
