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. You;ll learn the basics of base-2 conversions and binary values and examine classes A B C D and E which respectively allow you to portion a network into various different sizes. Finally you’ll learn about supernetting a more advanced form of subnetting as well as IPv6 concepts subinterfaces and virtual IP addresses
