Replied by durk21 on topic figured out how to explain it
255.255.0.0 or /16
Is in fact the broadcast address for the class A It is the last subnet in the series of subnets making up a Class A range.
Because
255.255.0.0 or /16 = 11111111.11111111.0.0
understand that?
so that makes
255.255.128.0 or /17
the first usable Class B Subnet. So 255.255.0.0 is just taught as a Class B to make teaching Subnetting easier.
So then
255.255.255.0 or /24
is the last usable Class B Subnet. At least this is how I am currently being taught in CCNA 2 and was taught in 1 through 4 which I've already taken and am doing so again.

well i guess u have some misconception on this subnetting and IP addressing. readout the document here in firewall.cx once again or from any other book.
and to check ur concept solve some problem from subnettingquestions.com.

tis is what 3 teachers and 6 books taught me. it works when subnetting it out because I've done it on the CCNA case STUDIES 5 times in fact. My explanation may be flaud but the math is not.
255.255.0.0 does in fact fall under a class A address because it is the last subnet in the the class A range. I have the CCNA study books from Cisco in which this is shown in their charts. And I hardly believe 3 Cisco certified teachers with 20 yrs of experienced could be wrong.
