Seriously, I have a /16 network but am blaming Elastix?

Funny. Whenever I see someone using /16, it's always 10.0.0.0. Like you can't use multiple /25 for example in that range...

Yeah, someone once heard that 10.0.0.0 was a Class A in 1992 and has carried on that misinformation for two and a half decade.

Yepp, but Class A is /8, not /16

According to http://www.subnet-calculator.com/subnet.php?net_class=A, the Class is determined by the first octet.

The first network I inherited was a 90.0.0.0/8 for private IP addresses! WTF?

Classes? CIDR is the only way to fly... or route I guess.

That's why I posted... CIDR has been the norm for the past few years as far as I can tell... Classes never really mattered anyway... Did they?

SAM mentioned classes, I was just explaining that a private class A network (10.0.0.0-10.255.255.255) is nothing else but 10.0.0.0/8

Sort of, but most often they were used as a means to explain address use for subnetting rather than being used as a literal standard in their own right.

Yepp. There's a reason that no one uses classes anymore. At least in theory:

It's not necessary... If it's not necessary, it's obsolete... and we all know what happens to obsolete stuff... (pause for effect) ... IT folks that don't know any better keep dragging it back from the brink of /dev/null.
