A component of network fundamentals, Subnetting prevents Ethernet collisions and conflicts in address assignment. Creating subnets allow an organization to divide the physical network into several logical networks. Network segmentation through subnetting allows for easier management and improved security. To be able to subnet, one first must understand binary to decimal conversion. Sub netting helps to create new IP addresses and this is especially important to know as IPv6 is in the works.
A solid understanding of subnetting is vital for managing your networks and the overall Security Architecture. The Cybrary “Create a Subnet” Course teaches how subnetting works, how IP addresses are broken down, and the purpose of subnetting in security and network administration, as well as what network components are represented. This course will also prepare you to explain network classes, dot-decimal notation, CIDR notation, subnet masks, and routing. The knowledge gained in this course will also allow us to create efficient IP spaces for our networks to minimize broadcasts.
Course Goals
By the end of this course, students should be able to:
Convert from Decimal to Hexadecimal to Binary
Know the Classful IPv4 network ranges
Subnet an IPv4 and IPv6 network
Utilize VLSM to “consume” an IP space
