How to check DNS propagation?

Through time, all businesses require changes to DNS records. But even you make such modifications fast, they won’t be visible immediately. This can be a bit frustrating, especially in urgent cases. Besides, taking too long could point to an issue. In any case, you will have to check how it is going.

Basics of DNS propagation.

DNS propagation is the time that it takes for DNS changes to be fully updated across the Internet.

Remember that modifications to DNS records can be made only on the authoritative DNS nameserver. And currently, most networks are really large. They integrate many servers, machines with different purposes, and all of them can be spread globally. 

With this image in mind, you can easily understand why changes, small or big ones, take time to be completed. They have to be updated on plenty of machines! 

Additionally, the process can face obstacles that can delay it even more. For instance, the DNS cache of the network’s servers. It totally contributes to making the network more agile, but it can delay the DNS propagation. They keep the most updated version of DNS records, during the time the TTL (time-to-live) each has configured remains valid. Once the TTL expires, recursive servers naturally will look for the last update. In other words, they won’t look for the update exactly at the moment you made DNS changes, but when their TTL points zero seconds.

The purpose of Domain Name System

Domain Name System – Definition

The Domain Name System is also frequently called shortly DNS, is a decentralized hierarchical infrastructure. Thanks to it, the Internet is as simple and easy for people as it is nowadays. At its core, it includes a database with all of the existent domain names and the IP addresses associated with them.

When a user wants to visit a particular website, types its domain name. That triggers a long DNS process for finding its IP address (IPv4 or IPv6). The domain name has to be translated because machines don’t communicate with words but only with numbers. After the corresponding IP address of the domain name the user wants to visit is found, the browser is able to connect to the website. 

Back in the days when the Domain Name System was not designed yet, it was a little bit more complicated to reach a website. It was necessary for users to type the long and difficult IP address, like 54.123.67.89, rather than a simple domain name, such as domain.com. Imagine what a memory challenge it was! The Domain Name system gave the opportunity for people to interact with the domain names and allowed machines to connect with their comfortable language (IP addresses).
