04 Try it yourself Interactive
The address analyser runs the exact procedure from section 02 on any address you give it, and every step shows the binary it operated on, because the binary is the teaching. The default is 172.16.94.221, so step for step it reproduces the worked example above. Then try the presets: a class A and two class C addresses, and the five that stop the procedure early — loopback, class D, class E, the limited broadcast and all zeros. Indigo bits are network bits, amber bits are host bits, and the rose bits in step 2 are the leading bits that chose the class. Nothing plays on its own — Next, Back and Reset, or the arrow keys.
