Some network administrators need to subnet quickly with a minimal amount of math. In this video, you’ll learn about the seven second subnetting shortcut for IP subnetting. << Previous: Magic Number Subnetting Next Video: Software Defined Networking >> In previous videos, we’ve gone through the process of manually converting an IP address and subnet mask […]

There are many different shortcuts that network administrators use to quickly calculate IP subnet information. In this video, you’ll learn about the magic number method of IP subnetting. << Previous: Calculating IPv4 Subnets and Hosts Next Video: Seven Second Subnetting >> If you’ve been with us with the videos just prior to this one, then

Understanding how to subnet using variable length subnet masks are important for any network administrator. In this video, you’ll learn how to use variable length subnet masks to segment a network into smaller IP subnets. << Previous: IPv4 Subnet Masks Next Video: Magic Number Subnetting >> In this video, we’re going to look at a

The transition to variable length subnet masks provides efficiency and flexibility with IP addressing. In this video, you’ll learn about classless subnetting and CIDR-block notation. << Previous: Classful Subnetting Next Video: Calculating IPv4 Subnets and Hosts >> In a previous video, we talked about class-based subnetting and how IP addresses can be assigned a class

We’ve designed IPv4 to support nearly any network size. In this video, you’ll learn the fundamentals of IPv4 subnetting and how network classes are used as a starting point for IP subnetting. << Previous: IPv4 Addressing Next Video: IPv4 Subnet Masks >> When you start working with IP version 4, one of the things you’ll

IPv4 is one of the most popular protocols in the world. In this video, you’ll learn about the fundamentals of IPv4 addressing, automatic IP addressing, and the difference between public and private IP addresses. << Previous: Binary Math Next Video: Classful Subnetting >> If you’ve done anything with networking, then you’ve probably run into an

If you’re calculating IP subnets, it will be useful to understand the basics of binary math. In this video, you’ll learn how to convert between decimal and binary IP addresses. << Previous: Network Architectures Next Video: IPv4 Addressing >> In the next part of this course, we’re going to talk a lot about IP subnetting.

Many networks are built using well-established design criteria. In this video, you’ll learn about three-tier architectures, collapsed core designs, and traffic flow in a data center. << Previous: Network Topologies Next Video: Binary Math >> Many enterprise networks take advantage of a three-tiered architecture. This is a very common design. And you’ll find many organizations

We often use broad descriptions when describing network topologies. In this video, you’ll learn about star, mesh, hybrid, spine and leaf, and other network topology types. << Previous: Copper Connectors Next Video: Network Architectures >> Networks can connect to each other in many different ways. And in this video, we’re going to look at a

Not every copper connection is the same. In this video, you’ll learn about RJ11, RJ45, F-connectors, and BNC copper connectors. << Previous: Fiber Connectors Next Video: Network Topologies >> One common copper connector we use on our networks today is an RJ11. This stands for Registered Jack type 11. It is a six-position connector, but
