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