Care should be taken when choosing to use Dynamic Host Configuration Protocol (DHCP), rather than a static IP address. DHCP mode is provided as a convenience when using units in informal settings or for test purposes. A static IP address should always be used when units are deployed in end-user installations. DHCP-obtained IP addresses depend on a lease to be maintained by the DHCP server in order to keep an assigned IP address. If the IP address lease is allowed to expire, there is a chance that the IP address assigned to one or more units could be lost, changed or reassigned, resulting in the loss of control or audio from a project.
The network administrator should be able to give you a range of static (or fixed) IP addresses to use for your project. When requesting these IP addresses, be sure to obtain enough to cover each unit.
