That was roughly my idea: come closer to the Emacs Lisp int
representation (whether only for this case or more generally).

But I'm not deep enough in Org to even venture a recommendation.

I definitely understand your surprise. I know it the other way
around. Back then (TM), it was customary in Windows to write out
the leading zeros in the IPv4 octets, to fill them up to three
places. Something like 192.168.042.001 -- Heavens knows why.

Unix utilities interpret those with a leading zero as an octal
representation (that's how atoi() or strtol() in its default
mode work). I had hours of fun with my Windows colleagues ;-)
