I guess I'm behind the times. Why do lightbulbs and toasters need
connectivity?
I suppose we can start using /22's now and make the DHCP pool 1000 IP's.
What's this about a holy war with IPv6? I haven't noticed that either.
Is there someone who thinks depletion is totally ok and we'll never need v6?

Yes, I know about IPv6 (and let’s not unleash that holy war), also
about smarthome hubs. But most people seem to be just buying stuff
like fridges and toasters and doorbells and lightbulbs and cameras,
and hooking them up to their WiFi router.
Almost any router you buy at the store is going to have a LAN subnet
like 192.168.1.0/24 and may not allocate all of that for DHCP range.
So there are at most 253 available addresses, and possibly as little
as 50 or 100. Until recently this should have been way more than
needed, but it seems inevitable that homes will soon have more than
253 connected devices.
May just mean switching to a bigger subnet, but average Joe doesn’t
know how to do that. Meanwhile if during the day his “things” have
taken the entire DHCP range and he gets home and his phone or laptop
can’t get an IP, he things it’s an Internet problem.
