For network engineers - IP CIDR and dot-decimal grid

This one is strictly for the network engineers. Noting the simple pattern in network masks, I sketched a grid to simplify the conversion of IP notation between dotted-decimal and CIDR notation, eliminating the need for a tedious CIDR listing of all 32 possibilities.

The dimensions are that of a US dollar, so it can be printed into a convenient wallet size.

Let me know if you find this useful.
