'whence' would be more specific – it's archaic in English, it means 'from where' – although it's used within the ksh shell.

‘whence’ is POSIX-reserved even in shells that don't implement it¹. (‘what’ is also in POSIX². And ‘who’ is on first³.)

zsh also implements whence

ksh as well. Found someone’s reference to various “what” type commands[1]:

> The whence command is a Korn Shell feature that tells how a name would be interpreted by the shell: it detects commands and aliases, and searches your path.

Perhaps 'whip' for 'what internet protocol'?
