If you run a website, it’s essential that you’re able to control who has access to your site and how they get there. Because DNS SOA records are so important to maintaining control over your domain name, it’s important to keep an eye on them at all times. You can do this by performing an SOA record lookup every month or so—to check them at regular intervals.
SOA record lookup is a good way to check the configuration of your DNS servers. It can help you find out whether there are any errors in your DNS configuration, or if the records are configured correctly.
