One of the most common Interview questions for Networking related positions involves asking a candidate what occurs in order to move data through a Network. This is a great question to ask, because it requires understanding all the fundamental working parts of how data moves through the Internet. I’ve interviewed hundreds of candidates. And I’ve… Read More »“Tell me everything that happens when you type google.com into a web browser”

Supernetting, IP Aggregation, and IP Summarization

Ed Harmoush — Wed, 26 May 2021 19:11:36 +0000

Supernetting is something like the inverse of Subnetting. With Subnetting, you take one Network and divide it into multiple sub-networks (subnets). With Supernetting, you are doing the opposite: you take multiple subnets and aggregating them into a single Network. Supernetting is synonymous to the terms IP Aggregation and IP Summarization. Often, training explicitly on Supernetting… Read More »Supernetting, IP Aggregation, and IP Summarization

Numbered ACL Configuration

Ed Harmoush — Mon, 27 Jul 2020 18:52:59 +0000

In Part 3 of the series on ACLs, we go through a live demonstration of the configuration of various Numbered ACL statements. We’ll use the syntax we learned in the prior video to create access list entries to match specific packets. In doing so, we’ll get to talk through some important concepts — the implicit… Read More »Numbered ACL Configuration
