DNS and IP addresses

When we visit a website, we are looking up one of the largest databases in the world known as the DNS – this stands for ‘Domain Name System’.

Every domain name on the Internet, such as www.google.com or www.facebook.com, is identified by a unique four-portioned string known as an IP address which looks like a series of numbers (eg. 192.168.0.1). Since IP addresses are difficult to remember, the Internet allows you to remember its domain name instead. The mapping of domain names and IP addresses is handled by, you guessed it, the DNS.

Without the DNS, the internet would collapse immediately! In order to understand it, you would need fundamental knowledge in domain names and IP addresses. Therefore, I’ve decided to present and teach these systems for my first internal expert presentation.

Why? It is imperative to have a basic understanding of the importance of these systems, especially when it relates to launching (or in developer-speak: deploying) websites. As part of our roles at Hardhat Digital, we provide web hosting solutions to clients and help them manage their DNS records efficiently.

In many cases, the client are unaware as to what DNS records are or where to get them, so we would need to gather and analyze as much information to ensure a successful website deployment.

Once it has been implemented, the DNS goes unnoticed (which is a great result!). If not, it could potentially cause a lot of issue and challenges. This is why it’s important to have basic knowledge on how domain name systems operate and understand its impact on website deployment.
