Document Summary

We might think of this using base ten weights: 1*4 + 1*2 + 0*1, or 6. 100002 is 1*16 + 0*8 + 0*4 + 0*2 + 0*1, or 1610. 100001112 is 1*128 + 1*4 + 1*2 + 1*1 = 13510.

(cid:863) ea(cid:272)h of the fou(cid:396) (cid:1012)-bit quantities that makes up the 32-bit address is written as a decimal number between 0 255: e(cid:454)a(cid:373)ple - 192. 168. 1. 23. Each 32-bit address consists of a variable length network portion in the top bits and a host portion in the lower bits. All hosts on the same network have the same network portion.
