IP Address Reference
28. IP Address Reference
In most applications, the IP addresses and other configuration parameters of the underlying Ethernet system
will not need to be adjusted by the end user. If a system requires advanced networking requirements,
however, such as the partitioning of a high-bandwidth Ethernet backbone into virtual local area networks
(VLANs), then a qualified network engineer may need to make adjustments to the default Ethernet con-
figuration of the Lake device and the computer running the Lake Controller software. This chapter provides
reference information pertaining to Ethernet configuration.
28.1 Network Essentials
Ethernet is a cost-effective and easy-to-configure system for networking personal computers, servers, local
area networks (LANs), industrial and professional equipment, and even provides the fundamental transport
backbone of the Internet. Since Ethernet is widely used for many applications, there are a number of rules
governing network configuration to ensure there are no conflicts between multiple devices.
IP addresses provide the unique identifier of each node (unit of network hardware) on an Ethernet network.
The address uniquely identifies the network that the node is on, as well as uniquely identifying the node on
that network. For example, this unique identifier ensures that personal computers all around the world do
not clog the Internet with messages intended for local data transfers.
Since Ethernet is used locally and globally, Ethernet standards reserve ranges of IP addresses for various ap-
plications. Public IP addresses are used on the Internet, and should not be used in LANs. A range of private
IP addresses have also been defined and set aside for use on internal networks. These private IP addresses
can be used on internal networks by anyone, as the Internet’s backbone routers will not route packets with
these addresses.
Lake devices and the Lake Controller software have been developed and tested for use on internal networks
that are not intended to be connected to the Internet. Therefore, we recommend that you use private IP
addresses when configuring the network.
28.2 Factory Reset Configuration
A factory reset Lake device will have an IP address set in the Automatic Private IP Address range
169.254.x.x with a subnet mask of 255.255.0.0.
Dante digital audio networking utilizes the Dante Discovery service to automatically identify all Dante
devices on the network. It is imperative that the Dante Controller, which includes installation of the Dante
Discovery service, is installed on the Lake Controller PC for Dante to function.
The default starting point is for all device to be left with this factory reset automatic IP address range, with
the Controller PC configured to obtain an IP address automatically. If problems are encountered, or you
require a more complex configuration, please refer to a network specialist, and in the case of a Dante audio
network, refer also to:
