Uncover the Technical Blueprint of Any Domain.
Before a browser loads a single word or an image, a hidden conversation happens using DNS records. These records—A, MX, TXT, NS, and more—are the fundamental address book and instruction manual of the internet. For SEO, marketing, and technical health, understanding them is crucial for diagnosing issues, verifying setups, and analyzing competitors.
Get Instant DNS Transparency with Our Free DNS Lookup Tool.
See the exact technical configuration of any website in seconds. Our powerful lookup tool queries global DNS servers to fetch and display all the essential records for any domain you enter. It’s your direct insight into server infrastructure, email security, and domain authority signals.
Why DNS Analysis is a Critical Technical Skill:
Diagnose Website & Email Issues: Quickly identify misconfigured A records (pointing to the wrong server IP), missing MX records (causing email delivery failures), or incorrect CNAME records breaking subdomains.
Verify SEO & Security Configurations: Check crucial TXT records for Google Search Console verification, email security protocols (SPF, DKIM, DMARC), and other service validations essential for trust and performance.
Analyze Competitor Infrastructure: Discover where a competitor hosts their website (IP/ISP), what email services they use, and if they utilize CDNs or advanced routing—valuable competitive intelligence.
Ensure Smooth Migrations & Launches: Before and after moving a website to a new host, verify that all DNS records (A, AAAA, CNAME, MX) have propagated correctly worldwide to prevent downtime.
From a Simple Query to a Detailed Technical Profile.
Our tool provides a clean, organized breakdown of all major record types:
A & AAAA Records: The core IP addresses of the website’s server (IPv4 and IPv6).
MX Records: The mail servers responsible for handling the domain’s email.
NS Records: The authoritative name servers for the domain.
TXT Records: Verification, security, and policy texts (e.g., SPF, DMARC, site verifications).
CNAME Records: Aliases that point one hostname to another.
SOA Record: The Start of Authority, containing admin info and refresh timers.
Your Diagnostic Protocol for Domain Health:
Enter the Domain: Type the domain name (e.g., example.com) you wish to analyze.
Run the Lookup: Initiate a comprehensive, real-time DNS query.
