Author - Lukasz Madrzak by Łukasz Mądrzak on August 11th, 2023

As a new website or online store owner, one of the first steps on your journey is selecting and purchasing a domain name. This domain name will serve as your unique address on the web, reflecting your brand and allowing visitors to find you easily. Once you have purchased a domain, understanding the basics of DNS (Domain Name System) becomes crucial for ensuring a smooth online presence.


A. What is DNS

DNS is essentially the phone book of the internet, translating human-readable domain names into IP addresses that computers can understand. Before you can configure DNS settings, it is necessary to have a domain name registered with a domain registrar. This process involves choosing a name that aligns with your brand, checking its availability, and purchasing it through a domain provider. Once you own a domain, you can move on to the more technical aspects of setting up and managing DNS.


B. The Importance of DNS Management

DNS management plays a crucial role in the overall performance and availability of your website or online store. When DNS is properly configured, your visitors will experience faster loading times and seamless browsing. On the other hand, a misconfigured DNS can lead to slow website performance, frequent downtime, and even potential security risks. Therefore, it is essential to proactively manage and monitor your DNS configuration to ensure optimal website performance.


C. Common DNS Issues and Troubleshooting

While DNS is generally reliable, there are some common issues that website and online store owners may encounter. One such issue is DNS propagation, which refers to the time it takes for DNS changes to propagate across the internet. During this propagation period, some users may experience difficulty accessing your website or online store. Fortunately, this issue is temporary and can be minimized by implementing best practices, such as reducing your DNS TTL (Time-to-Live) values.

Another common DNS issue is misconfigured DNS records. This can lead to various problems, such as emails not being delivered, subdomains not working, or SSL certificates not validating correctly. If you encounter these issues, carefully reviewing and updating your DNS records can often resolve them. Additionally, using DNS-specific troubleshooting tools, like DNS lookup tools or online DNS checker tools, can help identify and diagnose DNS-related problems.


D. Setting Up DNS Records

To set up DNS records for your website or online store, you'll need to access your domain registrar or DNS hosting provider's control panel. Generally, you'll need to create an A record to point your domain to the IP address of your web server, a CNAME record to set up subdomains or aliases, and MX records to handle email routing. It's important to follow the instructions provided by your DNS provider and double-check your settings to avoid any misconfiguration.
