Wireless ISP Network IP Scheme

For those of you starting out in the WISP field here is a good overview of a scalable Ip scheme for your WISP network. There are some caveats to this, which we will discuss later. This does not address IPV6, I have done some articles on IPv6 in the past that addresses IPV6.

Some benefits of this scheme
1.Logically separates equipment into groups.
2.Cookie-Cutter design. Fast time to depoyment
3.Easy to train on for techs and office
4.Scriptable

This following scheme uses private IP space for infrastructure. This scheme does not address end-user addressing. More on this in a later guide.

For each tower I route a /16 out of the 10.0.0.0/8 IP space. For example my first tower is
10.1.0.0/16 . Your first thought is that is alot of IP space. Yes it. However, it is private IP space and you can use as much as you want. The second thought is you can only use this scheme 255 times. Yes this is true. How many WISPs are growing beyond 255 towers. Most of the wisps I know are in the 100 tower sweet spot. There are larger and smaller wisps.

So lets break this down. We are using tower 1 as an example.

Wired Infrastrudture 
1-Not used due to default being VLAN 1 on most devices. Quarantine vlan 
10.1.2.0/24

2- Power and UPSes 
10.1.2.0/24

3- Switches and routers 
10.1.3.0/24

5-9 reserved for  future uses

Backhaul Management VLANS 

10-19 
10.1.10.0/24 – Backhaul 1
10.1.11.0/24 – BackHaul 2
etc.

90-99 – RESERVED possible IOT 

Customer VLANS (untagged) 

120-129 – 2GHZ equipment 
10.1.120.0/24 – Customer CPE on first 2.4GHZ AP
etc.

170-179 – RESERVED 

180-189 – 80 GHZ 

Point to Point customers 

200-299 

So why so much IP space? It helps keep your routing table small.
