to 1,500 subnets, you would need to determine which 2
x
is the first one that is greater than
or equal to 1,500. If you calculate your powers correctly, 2
11
(2
11
= 2,048) is the first one
that is greater than or equal to 1,500. So, you would add the power of 11 to the /53 in the
previous address, and you would now use /64 as your network mask. Table 8.8 shows you
some of the power numbers for the power of 2.

Summary
Why TCP/IP is the primary protocol in use today is one of the important topics covered in
this chapter. You also learned that the 32-bit IPv4 address is a structured and hierarchical
one that is used to identify uniquely every machine on a network. You learned how to
determine available IP addresses and implement subnetting. In addition, you learned how
the new layer 3 IPv6 protocol is implemented, including the structure of the IPv6 address.
Finally, I discussed the new functionality included in IPv6 addressing as well as several
Windows Server 2012 R2 integration/migration implementations.
