About DNS (Domain Name System) Info Tool
Understanding your DNS records is crucial for ensuring your website's accessibility, deliverability, and performance. Our lookup tool supports all essential record types including A, AAAA, CNAME, MX, NS, SOA, TXT, SPF, DMARC, PTR, CAA, Ping (ICMP), and Global Propagation. Start by entering your domain name or IP address above.
A valid DNS record is crucial for ensuring your website's accessibility and performance. Our DNS Checker allows you to inspect records like A, AAAA, CNAME, MX, NS, SOA, DMARC, SPF, PTR, TXT, CAA, SRV, and DNSSEC. Start by entering the domain name you want to verify. You can also check IP-related records like PTR (Reverse DNS) to verify mail server hostnames.
By using our DNS checker, you can quickly identify and resolve issues that may be affecting your website's performance. This includes checking for proper DNS configuration, identifying potential security risks, and ensuring that your DNS records are up-to-date and accurate. Learn more about DNS records here at iana.

Who Can Benefit from DNS Info?
Web Developers
Trace exactly how a domain resolves - from the root servers down to the authoritative name servers - and confirm your A, AAAA and CNAME records point where they should before you ship or migrate.
System and Network Admins
Verify delegation, name servers and propagation, watch the SSL and domain-expiry countdowns, and get an email the moment something changes.
DevOps and IT Professionals
Reverse-lookup IPs, inspect ASN / ISP / geo-location, validate DNSSEC and catch misconfigurations before they turn into an outage.
Email and Deliverability Teams
Check the records that decide whether your mail reaches the inbox - SPF, DKIM, DMARC and reverse-DNS alignment - all in one place.
Domain Owners and Registrants
Confirm your site is genuinely live (not parked, a placeholder or suspended) and never miss a domain or SSL-certificate renewal.
Everyday Users
Understand any domain at a glance: is it online, who hosts it and where it resolves - with fast, real-time answers.
Why Choose DNS Info?
Real authoritative resolution
We walk the live DNS tree - root to TLD to authoritative - and stream every hop as it happens, instead of handing back a cached guess.
Honest, evidence-based verdicts
SSL is checked with a real verified handshake (hostname, trust and expiry), and we tell you what a site truly is - live, parked, placeholder or down - not just “200 OK”.
Everything in one screen
DNS records, reverse DNS, SSL, site status, IP & ASN intelligence and email deliverability (SPF / DKIM / DMARC / DNSSEC) - one lookup, one view.
Continuous monitoring and instant alerts
Sign in and we’ll watch your domains around the clock, emailing you on downtime, SSL or domain expiry, and certificate-issuer or content changes.
Accuracy you can verify
Every answer comes straight from the authoritative servers, with the full trace and timing shown so you can trust it.
Shareable and convenient
Each result gets a unique shareable link, and the whole tool works on any device, anytime.
