Assigning Individual IP Addresses
After the Network Addresses have been decided upon, individual addresses within each network should be
assigned.
For the purposes of this example, Host A has previously been assigned an address of 1.0.15.12 and Host B has
previously been assigned an address of 1.0.15.13. The CAP’s External Interface must be assigned an individual
address on Network 1.0.0.0. For this example, it is assumed that address 1.0.15.14 has been chosen.
Data Advantage can auto-configure the individual IP addresses for its Internal Network and the EDACS Network.
While the defaults can be overridden by explicitly assigning individual addresses, it is simplest to let Data
Advantage do the work.

If a radio’s LID is changed, a new unit IP Address will be associated with the radio. If this is not desired, the mapping
can be changed.
NOTE
In this configuration Data Advantage and the Hosts are on the same network. In a more complex configuration,
there could be multiple gateways between Data Advantage and the Hosts. In this case, additional entries need to
be installed in the Data Advantage routing table to enable communication between the IP hosts and RDTs.
Regardless of the configuration, the CAP’s external IP Address must be a valid address on the network to which
it is connected.
Assigning LIDs to IP Hosts
In Data Advantage there is no need to assign an EDACS address to an IP host. If the EDACS Network Layer is
used, the EDACS Network Layer header includes the IP address of an IP host. If the EDACS Network Layer is
not used, Data Advantage obtains the IP address of the IP host using port-to-IP address mapping in the
configuration file. A None-Network Layer RDT must know which port(s) to send messages to in order to reach a
particular IP Host. Refer to the Data Advantage Technical Description Manual (see Preface) for detailed
information.
