There is lots of RFC1918 space out there, yet most people use the same 10 /24 subnets

I ended up having my OOB LAN collide with someones home network a few weeks ago, and decided to find a new subnet to use that won't collide backed up with actual usage data!

Picking uncontested private IP subnets with usage data

@benjojo I've sometimes wondered if the best way to avoid this problem is to squat one of the documentation networks. Or the benchmarking one

@erincandescent until someone later on tries to run a test inside your network using the doc prefix as a "safe test" :P

@benjojo @erincandescent my "I'm only half joking" suggestion is 240.0.0.0/4, hardly anyone is going to run tests on that

it'll probably work with Linux-based BMCs? has the advantage that Windows hosts politely refuse to send packets there, but has the disadvantage that Cisco routers also refuse to send packets there
