How Do I Update My DNS Server?


Larry Thompson

Updating your DNS server is an important task that ensures your website remains accessible to users. Whether you need to change the DNS records, point your domain to a new hosting provider, or troubleshoot DNS issues, this tutorial will guide you through the process step by step.

Step 1: Accessing Your Domain Registrar

To update your DNS server, you first need to access your domain registrar’s website. This is where you initially registered your domain name. Look for a login or account access link on their homepage and enter your login credentials.

Step 2: Navigating to DNS Management

Once logged in, locate the “DNS Management” or “Domain Settings” section in your account dashboard. Different registrars may have slightly different names for this section, but it generally contains the necessary options to manage your DNS records.

Substep 2.1: Selecting Your Domain

If you have multiple domains registered with the same registrar, you may need to select the specific domain you want to update from a list before proceeding.

Step 3: Updating DNS Records

In this step, we’ll focus on updating the various types of DNS records:

  • A Record: The A record points a domain or subdomain to an IP address. It is used for website hosting and mail servers.
  • CNAME Record: The CNAME record creates an alias for an existing A record or another CNAME record.
  • MX Record: The MX record specifies the mail server responsible for accepting email messages on behalf of your domain.

Substep 3.1: Updating A Records

To update the A record, locate the corresponding field and enter the new IP address provided by your hosting provider. Save the changes once you’ve entered the new value.

Substep 3.2: Updating CNAME Records

If you need to update a CNAME record, find the field for CNAME records and enter the new alias or destination domain. Click on “Save” or “Update” to apply the changes.3: Updating MX Records

When updating MX records, you’ll typically need to specify both a priority and a destination server. Enter the appropriate values in the fields provided and save your changes.

Step 4: DNS Propagation

After updating your DNS records, it’s important to understand that it may take some time for these changes to propagate across all DNS servers worldwide. This process, known as DNS propagation, can take anywhere from a few minutes to 48 hours.

Step 5: Verifying DNS Updates

To ensure that your DNS updates have been applied successfully, you can use various online tools such as “nslookup” or “dig” to query your domain’s DNS records and verify their accuracy. These tools provide information about which IP addresses are associated with your domain name.

Congratulations! You have successfully updated your DNS server. Remember to periodically check and update your DNS settings as needed, especially when migrating to a new hosting provider or making changes to your website infrastructure.
