Seriously, I have a /16 network but am blaming Elastix?
https://community.spiceworks.com/topic/1712402-anyone-use-elastix-pbx-software-beforeFunny. 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.

Just caught a Lapras about an hour ago on lunch! BOOM!

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.

Hell even now class usually just refers to large groups of what you'd notate with CIDR anyway. Like "It's a class A" "oh OK so I'll put 0.0.0.0/8". A definitely obsolete thing I hear very rarely is the different bytes being referred to as "octets", even though they're obviously written in decimal or hexidecimal. It just tells me they don't know what the hell octet even means and think it means byte or class or something.

IP Address = 4 decimal numbers = 4 octets... I got started calling them octets when I was taking my Cisco certs... and it just never went away, lol.

I used to talk octets.... to a PDP.

They are called octets I thought because it was eight bits. Why octet rather than byte, no idea, but they do the same thing with UNIX perms.

That's totally ok. An IPv4 address is made of 4 bytes, so 4x8 bit. 8 bits are an octet, so that's perfectly fine.

Yeah, never got used to it myself. It's like word vs short, dword vs int32, byte vs octet...

NodeBB 1.1 has just dropped.

I should clarify: these days if someone uses octet it means one of two things, either they're old as hell or deal with old as hell technology and/or companies, or they're young and completely ignorant and heard some old person say it. I never used it unless we're explicitly using base-8, which decimal IP addresses absolutely are not, if they were they highest you could go is 0255 or decimal 173.
