What is DNS propagation?

Let’s start with the propagation term. Think about your business. How long does it take to spread a new policy, philosophy, process’ change, etc., among all your employees? The process to communicate it from executives until the last employee in the chain takes some time. Right?

What is DNS?

Domain name system (DNS) is the infrastructure that makes it possible for humans to surf the Internet easily. Several processes take place through this system. DNS resolution is a big one. Every time you query a domain by typing its name, the browser requests it to a server. DNS translates that domain name into a numerical language (IP address) for machines (computers, authoritative servers, recursive servers…) to understand it, look for it, and make a match between the name and that IP address. If the match is successful, the domain is loaded for you.

Ping command explained

Ping command, what is it?

The Ping command is a great little utility tool with a simple command-line interface that serves for network diagnosing or, more precisely said – to probe a particular host or IP address (IPv4 address or IPv6 address) and see if there is a connection to it. 

With the Ping command, you are sending packets of data using the ICMP (internet control message protocol) from your device to a target. The packets will be 4 by default, each with a 32-byte size, and you will get the time it took each of them to reach the target. Another useful part of the statistics is that you will get minimum, maximum, and average time (in milliseconds) for the road. An interesting detail is that you will see a percentage of lost packets. You will also get the IP address of the target.
