What is “22 million”? I don’t understand. Is it length? Thousandths? An ion grinder? An exotic big cat? A tiny On?

“People don’t understand”, none of those were at all plausible even without the context of scanning the entire IPv4 address space.

The OP clearly states that it's about 22m responding internet protocols.

That surely is a lot of protocols.

22 cats. Go with cats.

Is that an abstraction of 22m meaning 22 mice, resulting in 22 cats? Clever. Very clever.
