This reminds me of the tale of the coder tasked to write an input validator for IPv4 addresses. Poor bastard.
Another fun one:
0177.042.017.066PSA: Don't zero-pad your IPv4 octets. Decimal is for simpletons.

Wait. Is that last one really home?
It's a Class A address, reserved for loopback devices. While not any sort of default - yes, it could be used as home :)
Keep in mind the modern ipv4 internet uses classless subnets so it is better to think of it as a /8
Yes. 127.0.0.0/8 is reserved IPv4 address space for Loopback. It is perfectly valid, and occasionally useful, to use other loopback addresses that are functionally identical, like 127.0.1.1 or 127.0.0.53, which carry semantic information for the initiated, like "53? Must be DNS-related, obviously!"
At the place I work, we use 10.127.0.0/16 for loopback addresses on networking equipment because it has that little familiarity from 127.0.0.0/8
Only with a /8 or 255.0.0.0 netmask. Which is not very common.
