CompTIA Network+ 2009: Network Addressing

This course is included in our On-demand training solution.


In order for devices to be part of a network, each must have at least one unique address. All network devices have a hardware address but communication is enabled through the use of logical addresses, most commonly IP addresses.
This course describes the two most common types of network addresses – MAC addresses and IP addresses. The details of IP addressing including how they are assigned, the different classes and how IP addressing is configured is explained along with the ways in which the shortage of IPv4 addresses is being dealt with. Solutions to the IP address shortage including the development and implementation of IPv6, network address translation, and Classless Inter-domain Routing (CIDR) is covered. This course also explains what subnetting is and how it is used to segment and organize networks.
This course maps to CompTIA’s Network+ (2009) exam objectives to evaluate the proper use of addressing technologies and addressing schemes.

Target Audience

The audience for CompTIA Network+ 2009 training will comprise IT personnel with at least 9 months IT networking experience. Good computer literacy along with a sound technical acumen should be present. Students looking to acquire job skills, and to be trained specifically to pass the associated CompTIA Network+ (2009 Edition) certification exam will want to study this learning path.
