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.
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.
|Richardson - Palisades||172.20.12.0/24|
|Denton Co EOC||172.20.17.0/24|
|The Colony Water Tower||172.20.38.0/24|
|Irving - Baylor S&W||172.20.72.0/24|
|N5ERS Tower - Grapevine||172.20.85.0/24|
|TWU - Guinn Hall||172.20.92.0/24|
|Little Elm Water Tower||172.20.201.0/24|
|Providence Water Tower||172.20.202.0/24|
|Delta V Instruments||172.20.204.0/24|
|TWU - Stark Hall||172.20.220.0/24|
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.
