Good point. My context is that of a version number. Adding trailing zeros will not affect the ordering of greater/less, but will affect exact matches using eq (I figured stripping trailing zeros to normalize before comparing for equality).

A function that takes an IP address as a buffer of 4 bytes, a v-string (which will UTF-8-encode the values above 127), or a string can tell the difference by looking for the presence of only digits and dots and of the total length.
