When I reading my MSCE books in the mid to late 90's /24 was the common thing. Now with understanding, etc I see the use of /22 and /23 and the advantages - but again, are their general networking books that everyone should be reading that we simply aren't?
Even the MS stuff in the 1990s told WHY /24 was used, so in reality they explained why it is too small today. Yes, /24 was common then, just like RAID 5, but since MS was clear as to why those were chosen and what factors were used, I'd say that they were pretty clear on why that is no longer true by the early 2000s.

A /24 is a silly thing on almost any SMB network. With the number of devices per user on a modern network you will smack that limit quick.

Even at home it's not hard to hit it quickly these days. I mean, not going to happen often. But between routers, switches, access points, mobile phones, VoIP devices, IoT devices, sensors, laptops, desktops, gaming machines, visitors, etc. and if you have a home lab with tons of VMs or containers, it adds up fast.

Yeah, its possible if every device is static and the lease time is unlimited.

Or they are just all on within a reasonable amount of time.

Plus you can have NAS, SAN and other storage things like that at home. Monitory, logging, etc.

What's the default lease duration in UBNT routers? I know Windows DHCP is limited to 8 days.

24 hours. I rarely leave it default though. I like 8 hours. If shit is going to break, I want to know about it sooner rather than later.
