Standard DNS Lookup
Troubleshoot Domain & Email Issues Instantly
When a website suddenly goes offline or critical business emails start bouncing to spam folders, the Domain Name System (DNS) is the first place you should look. Our Deep DNS tool allows webmasters, IT professionals, and business owners to pull live global domain records, bypassing local network caches to show you exactly how the internet sees your domain right now.
Stop Emails Going to Spam
Email deliverability is one of the most common headaches for modern businesses. If your emails are landing in your clients' junk folders, it is likely due to misconfigured security records. Use our Advanced Tools tab to instantly verify your SPF (Sender Policy Framework) and DMARC records. These records prove to email providers like Gmail and Outlook that you are the genuine sender, protecting your domain from being used in phishing scams.
Deep Network Diagnostics
Our standard lookup fetches all primary DNS records in seconds. Check your A Records to verify your website is pointing to the correct server IP address, or review your MX Records to ensure your email hosting is routed properly. We also include advanced security checks like DNSSEC to ensure your domain hasn't been hijacked or spoofed at the root level.
Why Use Our Diagnostic Tools?

Unlike your computer's command prompt, which caches old data, our tool queries global servers to give you the most up-to-date, real-time picture of your domain's health.
