DNS records are the backbone of how the internet connects domain names to servers. A wrong A record can break your website. A misconfigured MX record can block all emails.

With WHOIS Trackr’s DNS tool, you can fetch real-time records including:

• A, AAAA, CNAME
• MX, TXT, NS
• DNSSEC details

Use this to validate propagation issues, SPF/DMARC settings, or even catch hijacked subdomains. Even if you’re not a DNS expert, these records are crucial for uptime and email delivery.
