I prefer to think of it as paving the way for you to learn and deploy IPv6. You should thank me for making the IoT possible. :-p

The site ID piece gets confusing if you try to number by backhaul. I think it makes more sense to assign subnets by physical location. Tower site 1: 10.100.1.x/24 Tower site 20: 10.100.20.x/24 Tower site 30: 10.100.30.x/24 And so forth. This still lets you do something consistent like this: Tower site 1—Tower site 20 backhaul: 10.100.1.21/24<http://10.100.1.21/24> – local radio 10.100.1.22/24<http://10.100.1.22/24> – local router interface 10.100.20.1/24<http://10.100.20.1/24> – remote radio 10.100.20.2/24<http://10.100.20.2/24> – remote router interface Tower 1—Tower site 30 backhaul 10.100.1.31/24<http://10.100.1.31/24> – local radio 10.100.1.32/24<http://10.100.1.32/24> – local router interface 10.100.30.1/24<http://10.100.30.1/24> – remote radio 10.100.30.2/24<http://10.100.30.2/24> – remote router interface The biggest problem I had with using /30s was that unless I set up DNS, I lost track of what /30 belonged to what site once I had more than a handful of backhauls. Numbering this way, without DNS, all I have to know is what the site ID is.

But if you’re using private IP space, why limit yourself to /29s everywhere? Particularly if each site would have a site number, you could easily do: Site 33: 10.100.33.0/24<http://10.100.33.0/24> (.1 local radio, .2 local router, .101 remote radio, .102 remote router) Site 34: 10.100.34.0/24<http://10.100.34.0/24> (.1 local radio, .2 local router, .101 remote radio, .102 remote router) And so on… Leave yourself plenty of room and route bigger subnets. The site numbering idea might end up a little confusing, though, since “Site 33” is really TWO physical sites, and “Site 34” in my example above is TWO physical sites, one of which you’ve already called part of Site 33.
