Inspect and verify domain records across the global DNS system.

Enter a domain and click Lookup to see results.

What is DNS Lookup Tool

The DNS Lookup Tool is an online domain diagnostics utility designed to resolve Domain Name System (DNS) records. By querying Google's Public DNS infrastructure directly from your browser, it fetches active server mappings, nameservers, and verification codes for any specified domain name.

DNS functions as the directory of the internet, mapping human-readable domain names to computer-friendly IP addresses. Using this lookup panel, website administrators and web developers can inspect current DNS pointer configurations in real-time.

How to Use DNS Lookup Tool

  1. Input domain target: Type your target domain address (e.g., google.com or example.org) into the main input field.
  2. Select record category: Choose the record type you want to audit from the dropdown selection list (A, AAAA, MX, TXT, NS, CNAME, or ANY).
  3. Trigger the query: Click the DNS Lookup button or press the Enter key on your keyboard.
  4. Analyze record output: View the results rendered in a structured table displaying Name, Record Type, Time to Live (TTL), and data strings.

Key Features

  • Google API Integration: Direct connection to Google Public DNS API for fast and accurate DNS query resolutions.
  • Multi-record Support: Resolves core pointer types (A/AAAA), mail relays (MX), name authorities (NS), text verifications (TXT), and aliases (CNAME).
  • Live TTL Counter: Shows the exact Time to Live values (in seconds) indicating when recursive cache servers refresh the records.
  • Record Badges: Groups resolved results with color-coded badges for simple scannability and auditing.

Common Use Cases

  • Domain Propagation Audits: Verifying if a newly registered domain or updated DNS records have propagated to global servers.
  • Mail Servers Verification: Inspecting MX records during business email setup to prevent email delivery errors.
  • Security TXT Records Check: Auditing SPF, DKIM, and DMARC text strings on a domain to prevent email spoofing.

Frequently Asked Questions

Q: What does the "TTL" column mean in the results?
A: TTL stands for Time to Live. It represents the number of seconds a DNS record is cached by resolver servers before they query the authoritative nameservers for updates.

Q: What is the purpose of MX records?
A: MX (Mail Exchange) records specify the mail servers responsible for accepting emails sent to your domain. If these records are missing or incorrect, email clients cannot deliver mail to you.

Q: Why are TXT records used for security verification?
A: TXT records allow domain owners to publish arbitrary text. This is used by verification systems (such as search consoles) and security frameworks (like SPF, DKIM, and DMARC) to verify domain ownership and authorize email servers.

Q: Why does a change to my DNS records not show up immediately?
A: DNS changes require time to propagate. ISP resolver servers cache records based on their TTL values. A change will only be visible globally once the old cached records expire.
