-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''​.+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.
