Let i be your input.
Calculate t = -i.
If i is in the right format, t will have exactly one bit set.
Test this with t <> 0 and (t & i) == t
If that's ok, then your ans

Sorry for my stupidity but, maybe there is a function that converts mask
stored in int format to a numer of bits? ;)
Your function easyly convert this mask to dot decimal notation, but how
to count

Nothing built-in, and given the fact that "inet" no longer means "IPv4",
it's unlikely we'd add one in the future. But there's nothing stopping
you from adding one of your own. For example
