How to update your A-Records (DNS)

Posted on: 16th January 2023 | 1 min

Updating your DNS A-Records involves making changes to the DNS configuration for your domain. The process may vary slightly depending on your DNS hosting provider, but the general steps are as follows:

  1. Log in to your DNS hosting account. This is typically done through the website of your domain registrar or DNS hosting provider.
  2. Locate the DNS settings for your domain. This may be labeled as “DNS management,” “zone file,” or something similar.
  3. Find the A-Record for the host you want to update. An A-Record, or address record, maps a hostname to an IP address.
  4. Update the IP address associated with the hostname. If you’re pointing your hostname to a new IP address, simply replace the old IP address with the new one.
  5. Save your changes. This will typically be done by clicking a “Save” or “Update” button.
  6. Verify that the changes have taken effect. You can do this by using the command line tool nslookup or dig to lookup the DNS record of the hostname and check if it returns the correct IP address or by visiting the hostname in a web browser

It’s important to note that changes to DNS records can take some time to propagate, so it may take a few minutes or hours for your updates to take effect. Also, if your domain is using a DNS hosting provider different from your registrar, the steps may be different and you should check with the provider for instructions.

Additionally, It’s recommended to make a backup of your DNS records before making any changes. This will allow you to restore your previous configuration if something goes wrong.
