Which DNS servers does it query?

The tool queries public DNS resolvers to retrieve records. Results may vary slightly from what your local DNS cache shows.

Can I look up subdomains?

Yes. Enter the full subdomain (e.g., mail.example.com) to retrieve DNS records specific to that subdomain.

Does it show historical DNS records?

No. The tool shows current DNS records only. For historical DNS data, use a specialized DNS history service.

Is there a rate limit?

There is no strict rate limit for normal usage. However, avoid rapid repeated lookups as DNS servers may temporarily throttle the queries.

DNS Lookup

Name: DNS Lookup
Author: Zilita Team

Look up DNS records including A, AAAA, MX, TXT, NS, CNAME, SOA, and PTR records.

Introduction

The DNS Lookup tool queries the Domain Name System to reveal the complete DNS record set for any domain name. It retrieves A, AAAA, MX, TXT, NS, CNAME, SOA, and PTR records, providing a full picture of how a domain is configured across DNS servers worldwide.

What the Tool Does

Enter a domain name and the tool sends DNS queries to retrieve all available record types. Results are displayed organized by record type, showing each record's name, type, TTL (time to live), and value. The lookup covers mail server configuration (MX records), nameserver delegation (NS records), domain verification (TXT records), and IP address mappings (A and AAAA records).

Why It Is Useful

DNS misconfigurations cause some of the most frustrating and difficult-to-diagnose problems in web hosting: email not being delivered, websites resolving to wrong servers, SSL certificates failing to validate, and CDN configurations not taking effect. A complete DNS record view lets you identify these issues in seconds rather than spending hours checking individual record types through command-line tools.

Who Should Use It

System Administrators

Verify DNS configurations after making changes to nameservers, mail servers, or domain settings.

Web Developers

Debug domain resolution issues when websites are not loading correctly or SSL certificates show unexpected errors.

Email Administrators

Check MX record configuration and SPF/DKIM TXT records when email delivery problems arise.

IT Support Staff

Quickly diagnose whether a client's DNS issue is caused by missing records, incorrect IP mappings, or propagation delays.

Features

Full record type support: A, AAAA, MX, TXT, NS, CNAME, SOA, and PTR
TTL display for each record showing cache duration
Organized results grouped by record type with clear labels
Quick re-lookup button for checking propagation progress
No data stored — every lookup queries live DNS servers in real time

How to Use It

Enter the domain name you want to look up in the input field (e.g., example.com).
Click the Lookup button to initiate the DNS query.
Results appear within seconds, organized by record type. Scroll through to find the specific record type you need.
For ongoing troubleshooting, click Re-lookup periodically to check whether DNS changes have propagated.

Practical Examples

Email not arriving

A small business owner discovers email to their domain is bouncing. A DNS lookup reveals their MX records still point to a mail server that was decommissioned last month, identifying the root cause immediately.

SSL certificate error

A developer sees an SSL error when accessing a staging subdomain. The DNS lookup shows the subdomain lacks an A record and is resolving to the wrong IP, explaining why the certificate does not match.

Benefits

Replaces multiple command-line `dig` or `nslookup` queries with a single visual interface
Shows all record types simultaneously instead of requiring separate queries for each type
No installation required — works in any browser without terminal access
Provides a shareable, readable output format that is easier to discuss with non-technical stakeholders

Tips

Check TTL values to estimate how long DNS changes will take to propagate. Lower TTL values mean faster propagation.
Compare results from multiple lookups over time to confirm propagation is progressing as expected.
Pay special attention to TXT records when troubleshooting email — they often contain SPF and DKIM configurations that affect deliverability.

Frequently Asked Questions

Results are queried live from DNS servers at the time of lookup. They reflect the current state of the domain's DNS configuration.
