A domain is your website’s name on the internet, such as yourcompany.com, while DNS is the system that connects this name to the services used by the domain, including websites, email, and verification services.
When a customer enters your domain name in a browser, the browser does not understand the name directly. It uses DNS to find the server address it should connect to. For this reason, DNS settings are essential for operating a website and email service correctly.
The domain is the name users see, such as:
yourcompany.com
DNS is the collection of records and settings that tells the internet where services for that domain are located. Without correct DNS configuration, visitors may not reach your website, and email messages may not be delivered to your addresses.
Name Servers are servers responsible for storing and managing DNS records for a domain. When connecting your domain to hosting or an external DNS provider, you may be asked to change the Name Servers to values supplied by that provider.
Only change Name Servers when you have the correct values and clear instructions from your hosting or email provider.
An A record connects a domain or subdomain to a server IP address.
Example:
yourcompany.com → 192.0.2.10
It is commonly used to direct a website to its hosting server.
A CNAME record creates an alias for a domain or subdomain and points it to another domain name instead of an IP address.
Example:
www.yourcompany.com → yourcompany.com
It is commonly used to connect www to the main domain or to connect external services.
An MX record identifies the mail servers that receive email for a domain.
Example:
yourcompany.com → mail.yourcompany.com
If MX records are incorrect, incoming email delivery may be interrupted.
A TXT record is used to add text settings or verification values for different services, including:
DNS is commonly managed from the client area, domain control panel, or the DNS provider’s panel. Before editing any record:
After saving changes, the result may not appear immediately across the entire internet. This period is called DNS propagation, and its duration can vary according to record settings and internet providers.
During this period, some users may see the new configuration while others temporarily continue to see the previous one.
Correct DNS management helps keep your website, email, and digital services stable and secure.
