ASSIGNING NETWORK IP ADDRESSES
An internet consists of multiple networks connected together, with each network on the internet assigned a
unique network address. Therefore, the first step is to determine the IP Network Addresses that will be used. In
the simplest case, three network addresses will be used: one each for the IP Host Network, the Internal EDG
Network, and the EDACS Network. A Class A, B, or C address can be used for any of the addresses. Class D
and E addresses can not be used. Network Addresses can only be used once in an internet.

IP host internet with no IP addresses
If the IP Host Network already exists, its Network Address will have already been assigned. Otherwise it will
need to be assigned. For the purposes of this example, the IP Host Network is an existing network with an
address of 1.0.0.0.
Next, the internal EDG Network Address needs to be assigned. Since the number of individual addresses
required on this network is small (one address per board), a class C address is recommended. The EDG will
default its internal Network Address to 199.0.0.0. After verifying that this Network Address isn't used elsewhere
in this internet, it should be reserved with your Network Administrator. If this Network Address isn't available,
another Class C address can be used to conserve Class A and B Network IDs.
Finally, an available Network Address needs to be chosen for the EDACS Network. A Class C address typically
isn't used since each radio must be assigned an address, and most EDACS Networks have more than 254 radios.
A Class B address can be used to conserve Class A Network IDs. If an EDACS network ID is not specified, the
EDG will default to a value of 140.1.0.0.
