Network Topologies – CompTIA Network+ N10-007 – 1.5

We often reference our network topologies as standard types, such as star, ring, and mesh. In this video, you’ll learn about physical and logical network documentation using these standard network topologies. << Previous Video: Assigning IPv6 Addresses Next: Common Network Types >> If you’ve been tasked with creating some documentation of your network configuration, you

Assigning IPv4 Addresses – CompTIA Network+ N10-007 – 1.4

There are many different ways to configure a device with an IPv4 address. In this video, you’ll learn about DHCP, manual addressing, DHCP reservations, and APIPA. << Previous Video: Seven Second Subnetting Next: Assigning IPv6 Addresses >> In the early days of IP version 4, we would have to go from workstation to workstation to

IPv4 Addresses – CompTIA Network+ N10-007 – 1.4

Configuring IPv4 is more than just adding a single IP address. In this video, you’ll learn about the structure of an IPv4 address and the important configuration options to use IPv4 on your network. << Previous Video: Binary Math Next: Classful Subnetting >> As you’re configuring workstations, servers, routers, and other layer 3 devices, you’ll
