I doubt your understanding is correct. I think it more likely the ‘0/8’
this time was short enough to match /([^.]{1,3})$/ in the first regexp
and either:
- it has never been short enough in the past, e.g. ‘0/24’, or
- they've slipped through but not triggered an error for you to notice,
e.g. ipset's hash table didn't fill up.
