CompTIA Network+: IP Addressing Schemes and Subnetting
Computers and devices each require a unique identifier, known as an IP address, in order to participate on an IP network. Using a subnet mask, the IP address is divided into a network portion and a host portion. This practice is called subnetting and it allows for an IP network to be logically subdivided or segmented. In this course, you'll learn the fundamentals of public and private IP addresses and how to use Network Address Translation and Port Address Translation to translate addresses. Next, you'll examine the differences between IPv4 and IPv6 addressing, as well as various types of addresses including unicast, multicast, and anycast.
