<p dir="ltr">IP addresses follow classes out of tradition. Take the first octet, and convert it to binary. If it starts with a: </p>
<p dir="ltr">1, its a class E, which was never actually used.<br>
01, is class D, and is for multicast broadcasts.<br>
001 is class C, or /24, 255.255.256.0<br>
0001 is class B, or /16, 255.255.0.0<br>
And 0000 is class A, or /8, 255.0.0.0</p>

Hi,<br>
<br>
Occasionally I see something like <a href="http://192.168.0.0/24" rel="noreferrer" target="_blank">192.168.0.0/24</a>. The reference I am looking at now refers to the 24 as the class range. Is it actually the subnet?<br>
<br>
How do I convert this into the two IP's that make up the range?<br>
<br>
Thanks in advance for your help!!<br>
