How to Use Free Tools to Monitor Your Website’s DNS Records

DNS records tell the internet where to find your website. If they're changed without your knowledge, your site could be taken over or redirected to a scam. Monitoring DNS records is a simple way to stay in control.

What Are DNS Records?

DNS stands for Domain Name System. It's like a phonebook for the internet, matching domain names to IP addresses. Records include A records (which point to your server), CNAME records (for subdomains), MX records (for email), and more.

• A records tell the internet where your website lives.
• CNAME records link subdomains to main domains.
• MX records direct email traffic.
• TXT records can help with email security and domain verification.

How to Monitor DNS Records

You can use free tools to check and monitor your DNS records. These tools will show you what's currently set up and alert you if something changes.

• Use a DNS lookup tool like dnschecker.org or dnslookup.org to check your current records.
• Compare the results with what you expect. If something looks off, investigate.
• Set up alerts with tools like DNSMonitor or Cloudflare DNS to get notified if records change.

Why Regular Checks Matter

DNS records can be changed by hackers, especially if your domain is compromised. Regular checks help catch these changes early.

• A hacker might change your A record to point to a malicious server.
• An attacker could redirect traffic to a phishing site by altering MX records.
• If your DNS is misconfigured, your website might not load at all.

What to Do If You Find Something Wrong

If you notice changes you didn’t make, act quickly.

• Log in to your domain registrar or DNS provider and review the settings.
• Change any suspicious records back to their original values.
• Contact your web host or security team if you’re unsure what to do.
• Consider enabling two-factor authentication for your DNS provider account.
