Mmm.

It's pretty easy to put three IPv4 /24s on a sticky note on your monitor. I think it's not unfair to say that if one can remember every fact related to one's job, then one has a job with a very, very small scope.

Also, this is another great reason to use IPv6. The v6 documentation prefix is '2001:db8::/32'... plenty of space for example subnets and easy to remember.
