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 youÆll learn about supernetting a more advanced form of subnetting as well as IPv6 concepts subinterfaces and virtual IP addresses
