ICND1 2.0: Understanding IPv4 Addresses

There are various aspects to IP addressing, including calculations for constructing an IP address, classes of IP addresses designated for specific routing purposes, and public versus private IP addresses. There are also two types of IP addresses: IPv4 and IPv6. This course introduces the concepts behind IPv4 addresses. Subnetworks, or subnets, are very common in all but the smallest network environments, segmenting networks into smaller divisions that have their own addresses. To create subnet addresses, some of the bits that are used for the host portion of an IP address are "borrowed" to create the subnet address. This course concludes with describing how subnets function and how they are computed.

Target Audience
Interconnecting Cisco Network Devices Part 1 is essential for students preparing for the CCNA Routing and Switching or CCENT certifications. Students pursuing the CCNA Routing and Switching certification should complete parts 1 & 2 of the ICND learning path. Students pursuing the CCENT certification need only attend part 1 of the ICND curriculum. Anyone wishing to obtain Cisco Certified Network Associate (CCNA) 100-101 certification that validates the knowledge and skills required to successfully install, operate, and troubleshoot small to medium size enterprise branch network. Network administrators, network engineers, network managers, network designers, and project managers. Familiarity of navigating PC operating systems, the Internet, and basic IP addressing knowledge skills recommended.
