The
Transmission Control Protocol/Internet Protocol (TCP/IP)
suite was created by the Department of Defense (DoD) to ensure
and bottle abstracts integrity, as able-bodied as advance communications

We’ll activate by demography a attending at the DoD’s adaptation of TCP/IP and again analyze this version
and its protocols with the OSI advertence archetypal discussed in Affiliate 1, “Internetworking.”
Once you accept the protocols acclimated at the assorted levels of the DoD model, I’ll cover
IP acclamation and the altered classes of addresses acclimated in networks today.
Subnetting will be covered in Affiliate 3, “IP Subnetting, Variable Length
Subnet Masks (VLSMs), and Troubleshooting TCP/IP.”
Last, because advertisement addresses are so important to compassionate IP addressing, as well
as subnetting, and VLSM, an compassionate of the assorted flavors of advertisement addresses is
critical. I’ll accomplishment with the assorted types of advertisement addresses that you aloof charge know.
Internet Protocol adaptation 6 will not be discussed in this chapter; this affiliate will focus
solely on IPv4. IPv6 will be covered in Affiliate 13, “IP Adaptation 6 (IPv6).” Also, back discussing
