IP Addressing Scheme

With the increase of wide-area microwave networks supporting various VoIP and supplemental radio systems, it is necessary to standardize on an IP addressing scheme that can accommodate a switched network with multiple gateways.

Site Allocations

Each site should have its own /24 (172.20.x.0-172.20.x.254) address space. The digits in the “x” position are determined by a site identifier, such as a common repeater frequency. For example, the UT Dallas site uses the 172.20.43.0/24 address space because the K5UTD VHF repeater is on 145.43MHz. The K5RWK site uses 172.20.12.0/24 because of the 147.12MHz repeater.

If a site does not have unique digits to identify itself, it shall be assigned an address in the 172.20.200.0-172.20.254.0 address space.

Device Allocations

Different sites will be required to accommodate different classes of devices. It can be assumed that most sites will have a managed switch, at least one backhaul radio, and some devices that are connected to the network. Certain sites will have an internet gateway.
