Note:

Raymarine’s IP address range is for

local traffic

within the

vessel’s private Raymarine network only

, and does NOT traverse

across Raymarine products to external networks, or to the Internet.

• In a Raymarine Ethernet (IPv4) network, IP addresses are self-allocated

by certain Raymarine equipment in the following range:

198.18.0.32 to

198.18.3.255

(inclusive).

You must avoid placing any devices in this

range using manual (static) IP addresses.

• Whether your network includes only Raymarine Ethernet (IP) devices, or a

mixture of Raymarine and third-party Ethernet (IPv4) devices, you have 3
options for configuring the Ethernet (IPv4) network and managing the IP
addresses for your devices:

Use a Raymarine device as the sole DHCP server to allocate IP
addresses automatically to all Raymarine and third-party Ethernet
(IPv4) devices on the network.

For the purposes of simplicity and

reliability, this is the recommended option for most vessels.

The

following Raymarine devices can act as DHCP servers:

Raymarine multifunction display (MFD)

/ Chartplotter, running

LightHouse 3 or LightHouse 4; or:

Raymarine YachtSense Link Router

Note:

If both a Raymarine MFD

and

YachtSense Link Router are

present in the same network, the YachtSense Link Router MUST be
configured as the DHCP server for that network. To facilitate this, the
Raymarine MFD's DHCP setting defaults to

Automatic

as standard. On

power up, if the YachtSense Link is detected in the RayNet system,
any MFDs in the network will disable their own

DHCP Server

, to

permit the YachtSense Link to manage the network's IP addresses.
Only Raymarine MFDs running

LightHouse 4

are compatible with the

YachtSense Link Router. Additionally, the most recent versions of the
LightHouse 4 and YachtSense Link software must be used.

2. Use a third-party Ethernet (IPv4) device (such as a router or Access

Point) to allocate IP addresses automatically, as a sole

DHCP server

To do this, refer to the

Configuring a third-party router as DHCP server

section, below.

Note:

Any Raymarine LightHouse 3 or LightHouse 4 MFDs will

still self-allocate their own IP address, even if a third-party DHCP
server is being used to allocate IP addresses to other Raymarine or
non-Raymarine

DHCP client

devices (Camera, Radar, Sonar etc.) on

the network.

Manually configure static IP addresses for your devices. The address
range

198.18.0.32 to 198.18.3.255

(inclusive) is used by Raymarine

equipment, and any other third-party equipment on the network should
not be set to a static IP address in this range. It should instead be set
elsewhere in the 198.18.0.0/21 range.

Adding third-party devices to your Raymarine Ethernet (IP)
network

• It is recommended that any third-party products connecting to a Raymarine

Ethernet (IPv4) network (e.g., a third-party IP camera) are configured as
DHCP clients, so that they automatically get allocated a correct IP address
within the range used by the

Raymarine IPv4 network

. If this is not

possible, (for example, in the scenario that your third-party IP Camera
requires a static IP address), you should configure the product to have
a static IP address within the following range:

198.18.0.1 to 198.18.0.31

(inclusive).

• Any third-party router in your network should be performing IPv4

Network

Address Translation

(NAT) from the private address to another one on an

upstream interface.

Configuring a third-party router as DHCP server

In the scenario that you wish to use a third-party DHCP server to allocate the
IP addresses for your vessel’s IPv4 network, use the following information
to help you configure the third-party DHCP server to work with Raymarine
Ethernet (IPv4) client devices:

Configure the third-party DHCP server / router to use Raymarine's subnet
details, which are as follows:

Set the DHCP server's IP address to

198.18.0.1

Set the

netmask

to /21, i.e.

255.255.248.0

Set the DHCP range from

198.18.4.0 to 198.18.7.254

(inclusive). If

this is not possible, ensure that the address range is smaller than this
(but within the range of

198.18.4.0 to 198.18.7.254
