6.3 Multiple Physical LANs and the Same IP Sub-Network
Sometimes it may not be possible to obtain multiple blocks of IP sub-networks for the Cyan nodes even if
they do not share the same physical LAN segments. In such cases it is possible to assign IP addresses from
the same logical IP sub-network to Cyan nodes and have them communicate with the Planet Operate server.
This section describes the various options available for configuring the DCN based on the location of the
Planet Operate server.
Collocated Planet Operate Server
The diagram below shows a collocated Planet Operate server and Cyan nodes.

The following options can be considered for the network configuration example shown above:
•
Proxy ARP
(Cyan recommended option)
Enabling proxy ARP support on the gateway Cyan node enables the Planet Operate server to
communicate with the other Cyan nodes without any additional configuration in the router or the
Planet Operate server.
