Network Defense Best Practices

network plus Apr 17, 2018

Today's networks face many security threats. The good news is, even without being security experts there are some best practices we can put into place to better protect our networks.

In the latest episode of my podcast, called The Broadcast Storm, you'll learn about a collection of common network threats and best practices to defend our networks.

The specific network threats and mitigations discussed in this episode come from topics CompTIA identified that we need to know for the latest version of their Network+ certification.

The Fundamentals of IP, ICMP, UDP, & TCP

ccna r/s network plus May 03, 2016

In this video we’re covering the fundamental concepts surrounding the IP, ICMP, UDP, and TCP networking protocols. Having a solid understanding of these protocols is critical to just about everything else we do in networking. So, I thought it would make a great review for you.

Enjoy the video!

How to Calculate an EUI-64 Address

ccna r/s network plus Feb 09, 2016

An IPv6 address is 128 bits in length, and like an IPv4 address, it’s divided into prefix bits (representing the network segment) and host bits (uniquely identifying a host on that network segment). A common approach is to use 64 bits to represent the network segment and 64 bits to represent the host on that network segment.


While you could manually configure the host bits for a router interface, a more efficient approach might be to automatically calculate those host bits using a 64-bit Extended Unique Identifier, known as EUI-64. For example, let’s say you have a router interface on the IPv6 network of 2000:1::/64. You could (in interface configuration mode of your Cisco IOS router) enter the command:

ipv6 address 2000:1::/64 eui-64


This command tells the interface to use 2000:1:: as the network portion of the IPv6 address and to automatically calculate the 64-bit host portion of the IPv6 address.

EUI-64 uses an interface’s MAC address as the basis of...

Introduction to Storage Area Network (SAN) Technologies

network plus Aug 20, 2015

Storage Area Networks (SANs) allow devices (e.g. PCs or servers) to store and retrieve data from hard drives that are attached somewhere on a network, as opposed to being directly attached to the device itself.

This video introduces you to the exciting world of SAN technologies.
