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:
