How does IP get our data from one side of the network to the other? In this video, you’ll learn about the fundamentals of IP and how IP addresses and port numbers are used on our modern networks. << Previous Video: Configuring IPv6 Next: Common Ports >> The data networks that we’ve created allow us […]

The need to subnet is minimized in IPv6, but there are still subnetting fundamentals that are important to know. In this video, you’ll learn about IPv6 subnetting and how most networks implement IPv6 subnet masks. << Previous Video: IPv6 Addressing Next: Configuring IPv6 >> On the internet, we have a formal process on how IP

Before you can use a shortcut to calculate subnet values, it’s useful to understand the binary math. In this video, you’ll learn how to calculate the important values of an IP subnet based on the IP address and subnet mask. << Previous Video: IPv4 Subnet Masks Next: Magic Number Subnetting >> In this video, we’ll

The IPv4 subnet mask determines which devices are on your local IP subnet. In this video, you’ll learn about the structure of the IPv4 subnet mask and how to calculate the subnet mask based on binary and CIDR-block notations. << Previous Video: Classful Subnetting Next: Calculating IPv4 Subnets and Hosts >> In this video, we’re

The IP addressing process can be statically configured or automatically assigned. In this video, you’ll learn about the components of an IP address, special IP addresses, DHCP addressing, and APIPA configurations. << Previous Video: Binary Math Next: Network Address Translation >> If you’re configuring IPv4 on a computer, then you need to configure three very

There are many ways to implement an Ethernet network. In this video, you’ll learn about the different speeds and connectivity types for popular Ethernet standards. << Previous Video: Cable Management Next: Binary Math >> By far, Ethernet has to be the most popular networking technology in the world. It is used in practically every organization

There are many different connectors used on fiber and copper network links. In this video, you’ll learn about the various kinds of connectors that are used on common networking equipment. << Previous Video: Optical Fiber Next: Network Transceivers >> One popular fiber optic connector is the LC or local connector. This connector has two different

Network administrators work with many different types of copper cables. In this video, you’ll learn about cable categories, coax, twinax, and 568A and 568B termination standards. << Previous Video: Provider Links Next: Optical Fiber >> Copper cabling is the foundation of our Ethernet networks. If you have a network at home, you’re usually connecting with

There are many different ways to connect with a network provider. In this video, you’ll learn about satellite networking, copper, DSL, cable broadband, fiber, and metro Ethernet links. << Previous Video: Virtual Networks Next: Copper Cabling >> We often think about connecting to the internet using a local wireless connection or a wired Ethernet cable.

Just as servers have moved to virtual systems, our networks have also become virtualized. In this video, you’ll learn about network function virtualization (NFV), hypervisors, vSwitches, and virtual network interface cards (vNICs). << Previous Video: WAN Termination Next: Provider Links >> The way we’ve managed data has changed rapidly over the last few years, and
