Frequently Asked Questions
What DNS record types can I look up?
A (IPv4 address), AAAA (IPv6), MX (mail server), CNAME (alias), TXT (verification, SPF, DKIM), NS (nameservers), SOA (zone authority), PTR (reverse DNS), CAA (cert authority), SRV (service locator).
How long do DNS changes take to propagate?
DNS changes propagate based on the record's TTL (Time To Live). Low TTL (300 seconds) propagates in minutes. High TTL (86400 = 24 hours) takes up to 24 hours to update globally. Check the current TTL value in your lookup results.
How do I verify my SPF record is set up correctly?
Look up TXT records for your domain. Your SPF record starts with "v=spf1". A valid SPF might look like: v=spf1 include:_spf.google.com ~all. Use an SPF validator tool for detailed syntax checking.
What is a CNAME record and when should I use it?
A CNAME (Canonical Name) is an alias that points one domain to another: www.example.com → example.com. Use CNAMEs for subdomains pointing to CDNs or third-party services. You cannot use a CNAME on a bare domain (zone apex).
What is the difference between A and AAAA records?
A records hold IPv4 addresses (e.g. 93.184.216.34). AAAA records hold IPv6 addresses (e.g. 2606:2800:220:1:248:1893:25c8:1946). Sites with both A and AAAA records support dual-stack IPv4/IPv6 connections.

How does the Consulta DNS work?
Consulte registros DNS (A, MX, TXT, NS, CNAME) de qualquer domínio. Your input is processed on Cloudflare's edge infrastructure — it is not stored, logged, or shared with any third party.
Do I need to install anything to use the Consulta DNS?
No installation needed. The Consulta DNS runs entirely in your web browser on any device — desktop, tablet, or mobile.

Does the Consulta DNS work offline?
No — the Consulta DNS processes your input on Cloudflare's edge servers and requires an internet connection.
How current is the data returned by the Consulta DNS?
The Consulta DNS fetches live data in real time each time you run it. Results reflect the current state of the server or domain at the moment of the request.
Why does the Consulta DNS sometimes return different results than other tools?
Results depend on the real-time state of the target server and DNS propagation, which can vary by geographic region and caching TTL. If you see inconsistencies, wait a few minutes and re-test — DNS changes can take up to 48 hours to propagate fully worldwide.
Does the Consulta DNS work on all browsers?
Yes. The Consulta DNS is built with standard browser APIs and works on all modern browsers including Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or third-party software are required.
How do I save or export my results from the Consulta DNS?
Select and copy the result text to paste into any document or app. For image tools, a Download button saves the file directly to your device. Your browser's built-in screenshot function also captures results quickly. No account or login is required.
