That's only true because people have learned a lot of bad habits with IPv4.
No, it's because IPv4 addresses are annotated as x.x.x.x
Sticking with class size masks makes it easy to separate the network
address part from the device address part.
But then we get to the situation that led to the question in this
thread, where people think the available addresses depends on which
address range they're working with. As long as the subnet size fits
within the allocated space, there is no problem. However it is better
to think of address space in terms of need. For most, that would be a
/24, as is commonly provided. It makes absolutely no difference whether
that /24 is in the 192.168.0.0 /16 or 10.0.0.0 /8 blocks. If you really
need more, then just think of subnet mask size.
