   Why ".1.1", and not ".0.0"?  "a.b.0.0:255.255.0.0" would cover what
_I_'d call the whole "a.b.*.*" range.

   I'll try again.  Define "IP".

      https://en.wikipedia.org/wiki/Internet_Protocol
      https://en.wikipedia.org/wiki/IP_address

If you _mean_ "IP _address_", then your meaning would be clearer if you
_said_ "IP address".

> [...] I was told [...]

   Trust no one, I always say.  "SHOW" is your friend.

   Odd, and annoying.  I'd be happy to ditch my handy mask-guide
comments.

   Another related annoyance is that where that notation _is_ accepted
(like, say, SYS$SPECIFIC:[TCPIP$SMTP]TCPIP$SMTP.CONF), the whole address
must be specified, including the insignificant part.  I've repeatedly
gotten bad data using copy+paste (carelessly) from whois.ripe.net or
whois.lacnic.net, which publish values like "186.188.128/17" instead of
"186.188.128.0/17", where the last ".0" conveys no useful information. 
As an aside.
