4 IP Network Planning
CAP15, CCU03 Ethernet port
• As noted above, the IP addressing plan for each CCU radio subnet should allow for
growth to a maximally equipped system. Providing 601 IP addresses on the same
subnet requires a subnet with a 22-bit mask, for example 172.16.0.0 / 22.
In the example shown in
radio subnets is summarized in

• The end-user PC Ethernet IP address can be entered statically, or dynamically using
DHCP. If DHCP Relay is enabled in the CCU, which WaveRider recommends, and the
system operator has installed and properly configured a DHCP server in the network,
then the end-user computer can be simply configured to automatically request its IP
address from the DHCP server. The operation and configuration of DHCP Relay is
discussed in
allocate, for each CCU radio subnet, a pool of IP addresses from the CCU subnet,
such as the contiguous sets of end-user PC IP addresses defined in
• If you are using unregistered IP addresses for the EUMs and end-user PCs, these
addresses must be translated to globally unique Internet registered addresses before
they leave the private domain. Although the CCU functions as a router, it does not
provide address translation.
For end users to access the Internet, you must provide NAT (Network Address
Translation). Normally, NAT is provided in the gateway (NAP) router. Refer to
4.3, Network Address Translation for further information.
