Global DNS Lookup & Propagation Checker

Query authoritative domain records directly using DNS-over-HTTPS (DoH). Troubleshoot email routing, diagnose server migrations, and verify SPF/TXT configurations instantly.

📡 The Phonebook of the Internet

The Domain Name System (DNS) translates human-readable domain names into machine-readable IP addresses. When setting up a new website, migrating a server, or configuring professional email (like Google Workspace or Microsoft 365), you must modify these underlying records.

Why is my site showing the old server? (TTL Explained)
Every DNS record has a Time To Live (TTL) value measured in seconds. If a record has a TTL of 3600, ISPs around the world will cache that record for 1 hour. This tool exposes the exact TTL, allowing you to estimate when a recent change will fully propagate across the internet.

🛡️ Powered by DNS-over-HTTPS (DoH)

Traditional DNS queries are sent in plaintext over UDP port 53, making them susceptible to interception, spoofing (DNS hijacking), and caching interference by your local ISP. This tool operates differently:

Bypassing Local Caches Because requests are wrapped in an encrypted HTTPS payload and sent directly to Google’s Public DNS API, you bypass your computer’s local DNS cache and your router’s outdated records, giving you the true, global state of the domain.

Evading Corporate Firewalls Many enterprise firewalls block standard command-line tools like dig or nslookup. By performing the query entirely over standard web port 443, you can perform deep network diagnostics even in heavily restricted environments.

❓ Common Record Types

A / AAAA Records:
The fundamental records mapping a domain to its IPv4 (A) or IPv6 (AAAA) address. Essential for web hosting.

MX & TXT Records:
Mail Exchanger (MX) records direct email to your mail server. Text (TXT) records hold arbitrary strings, primarily used for email security policies (SPF, DKIM, DMARC) to prevent your emails from going to spam.

Diagnostic Note: This tool performs external lookups via encrypted DoH APIs. Your local network restrictions and DNS blackholes (like Pi-hole or AdGuard) will not interfere with the results displayed here.
