IP HOST CONFIGURATIONS
Assigning Network IP Addresses
An internet consists of multiple networks connected together, with each network on the internet assigned a
unique network address. The first step in setting up an internet 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 Data Advantage 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. A Network Address can only be used once in an
internet.

If the IP Host Network already exists, its Network Address will have already been assigned. Otherwise it will
need to be assigned. For this example, the IP Host Network is an existing network with an address of 1.0.0.0.
Next, the Internal Data Advantage 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. Data
Advantage will default its internal Network Address to 192.168.100.0. If this Network Address isn't available,
another one can be used.
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 even a single site EDACS System can 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, Data Advantage will default to a value of 172.16.0.0. For this example, it is assumed that you
have chosen to assign Network Address 128.1.0.0 to your EDACS Network.
Remember that since each Network Address must be unique, the addresses selected should be reserved with the
Network Administrator so that they are not used elsewhere on the internet.
