[...] By full IP range, I meant a.b.1.1 through a.b.255.255. [...]
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.
[...] IPs is just a single IP regardless of subnet mask.
I'll try again. Define "IP".
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.
Somewhat odd that CIDR syntax (e.g. 192.0.2.0/24, 198.51.100.0/28) was
never added here, as an aside.
Odd, and annoying. I'd be happy to ditch my handy mask-guide
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
"188.8.131.52/17", where the last ".0" conveys no useful information.
As an aside.
