3.3.2.1 – IP Auto Assignment
*Note: The CobraNet protocol does not require each device is allocated an IP address. Once configured, audio will pass
between devices whether the devices have been allocated an IP address. This is because CobraNet audio transfers are done
just using device MAC addresses. However, in order to configure a CobraNet device, it must be assigned an IP address.
In order to be configured, each CobraNet device must have an IP address. That IP addresses can be set either statically or
dynamically. When configured with a static IP address, the device will always use the same IP address every time it is
powered up or reset. However, with a dynamic address, the CobraNet node is relying on a service on the network to supply
it with its IP address. In a normal network, this service is called a DHCP server. However, most CobraNet networks don’t
have such a facility available. Fortunately, Control Center has an auto IP assignment facility for those CobraNet systems that
need one.
This option should therefore be selected based on the needs of the system. In most systems, Control Center should be set
up to allocate IP addresses to CobraNet devices and so this option should be left selected. However, for systems that
already have a method of IP address allocation, this option should be turned off.
*Note: Setting up Control Center to provide automatic IP assignment has no effect on devices already with an IP address.
The devices will continue to use whatever IP address they were given, irrespective of the method used to obtain it, regardless
of whether Control Center auto assigns IP addresses or not.
3.3.2.2 – IP address Range
This option only takes affect it automatic IP assignment is enabled. It represents the range of IP addresses that Control
Center can give out. The “Default Range” button can be used to select a typical range of compatible addresses for the
selected NIC. However, values can be typed in to manually override the defaults if required.
