Approximately every home wifi router I've ever used has a class C subnet configured by default, out of the box.
That's enough for over 250 networked widgets to be concurrently connected with IPV4. That's a lot of widgets for one home.
If a person is getting into the realm of having a home with more than 250 networked widgets and addressing is becoming problematic in ways that are beyond their understanding and/or ability, then:
I might suggest that this is roughly equivalent to any other household thing that a homeowner doesn't fully understand (or that they don't want to understand), and that it would be completely fair to remind them that it is perfectly normal and acceptable to hire a qualified person or company to -- you know -- look into that for them.
(It's ok to hire a plumber, or a roofer, or a painter, or a cleaner, or any number of other professionals to help with making stuff work. It's also OK to hire someone to work on the network.)
