I was apprehensive about the trailing . in some of the partial IPs, but checked it and it doesn't seem to make any difference.
There's some very old discussion on this, however I've no clue what to search that would result in the threads.
I use the trailins DOT in everything for "deny from IP's".
The early logic was similar to a trailing slash in robots text (include all).
I seem to recall some early access errors (2000 or 2001) when omitting the DOT.
Apache and the change from POSIX to PCRE has an effect, I'm sure.
In any event the logic is that it works either way in present day, or so Jim stressed many times.
