You're at home.Some sites have way more machines in it.
My computer. g/f's computer. 2 laptops. PDA. Fridge. Microwave. Hifi. Telly. Sauna stove controller. ...
Um, do you have an internet-enabled microwave and fridge or are you just looking into the future? We're a 2-person household. The DNS configuration file of my home server has 31 devices listed. If I remove old (non-used) devices and double-counted ethernet/wifi, I still have 17 devices. And I'm not counting a block of addresses reserved for VPN: 1 desktop, 2 laptops, 2 tablets, 3 Android media players, audio system, cable decoder/DVR, 2 smartphones, e-reader, modem/router, wifi access point, home server, printer, Wii.
Within a couple of years, I can well imagine network access for IP cameras, home automation (temperature, window shutters, lighting). I still wonder why I would want to have a network-enabled fridge or microwave oven, though.
You have a networked microwave but you still use a PDA? *snort snort* What does it run, NetBIOS? *snort pushes glasses back up*
What, no toaster? :P
