Check DNS propagation across multiple global nameservers in real-time
đ¯ Domain & Record Type
Quick test:
âšī¸ How it works: This tool queries DNS using DNS-over-HTTPS (DoH) from your browser.
â ī¸ Browser Limitation (CORS): Most DNS providers block queries from websites
for security reasons. Only providers with CORS enabled (like Cloudflare) will work. Failed
queries don't mean your DNS is broken - they mean the provider is blocking browser-based queries.
đĄ For comprehensive checking: Use external tools like
WhatsmyDNS.net or
command-line tools like dig
or nslookup.

đ Why Do Most Queries Fail?
CORS (Cross-Origin Resource Sharing): Browser security prevents websites from querying most DNS providers
This is intentional: DNS providers block browser-based queries to prevent abuse
Only Cloudflare allows it: Cloudflare has CORS enabled for public use
Your DNS isn't broken: Failed queries mean the provider is blocking browser requests, not that your DNS is wrong
