What is DNS?

DNS (Domain Name System) functions as the internet’s phonebook. When a user enters a domain name into their browser (e.g., example.com), DNS translates that human-readable domain into the corresponding machine-readable IP address that identifies the actual web server (e.g., 192.0.2.1). This process enables users to access websites using easy-to-remember names instead of numerical IP addresses.

DNS is a foundational part of how the internet works. Without DNS, users would be required to remember complex IP addresses to reach websites. For a deeper understanding of DNS and how it works behind the scenes, refer to this guide by Verisign.

DNS Records (Domain Name System Records) are stored instructions that define how a domain should behave. These records are managed through DNS servers and play a critical role in directing internet traffic. Each record type serves a unique function, such as routing web traffic, handling email delivery, or verifying ownership of a domain.

There are many types of DNS records, but for most website configurations - including integration with MaxiSafe - the most commonly used are A and CNAME records. To learn more about DNS record types and their functions, visit IBM’s DNS Records Overview.

For MaxiSafe configuration, you will be mostly using either A or CNAME records to configure your website:

• CNAME Record (Canonical Name Record): A type of DNS entry that tells your subdomain (e.g., www.yourdomain.com) to point to another domain - in this case, our CDN endpoint.
• A Record (Address Record): The record that connects your domain directly to an IP address of your application server(e.g., google.com → 172.217.26.78). It's commonly used for root domains.
