Expertise Level


In this course, you will examine IP (Internet Protocol) addresses, which are assigned to network-equipped devices that are part of a TCP (Transitional Control Protocol)/IP-based network. Learners explore the basics of IP addressing and networking concepts such as DNS (Domain Name System), DHCP (Dynamic Host Configuration Protocol), and NAT (Network Address Translation). Begin with an overview of DNS and its benefits. Then, take a closer look at the DHCP, its features and reservations. Explore some of the basic characteristics of IP version 4, the fourth revision of the Internet protocol. Next, look at IP version 6, the successor to version 4; version 5's functionality was worked into version 6. Study the purpose of the Subnet Mask, a key component of IP address configurations, and the Default Gateway, commonly found as a value in an IP configuration. Recognize when to use VPNs (Virtual Private Networks), and look at virtual local area networks, or VLANs. Finally, explore the benefits of NAT. A closing exercise assesses skills in configuring network settings and components. This course can be used to help prepare for the 220-1001: CompTIA A+ certification exam.
