 +The power of ''​2''​ is also evident when crossing the first 256 # of IP addresses. ​ If starting at ''​192.168.1.0'',​ and extending to ''​512'',​ then you're only adding one set of ''​256''​s. So ''​1.0''​ would expand to ''​2.0''​. But what if you wanted to add more? The power of 2 applies, so you'd then have to jump by ''​4'',​ next. ''​192.168.1.0''​ now goes to ''​192.168.4.0''​. The next one would be ''​4''​ times ''​2'',​ so 8 is the next possible block. Going from ''​192.168.1.0''​ to ''​192.168.8.0''​. And so on, and so on: ''​192.168.16.0'',​ ''​192.168.32.0'',​ ''​192.168.64.0'',​ ''​192.168.128.0'',​ etc.
