FAQ

Q1: How long does DNS propagation take?

DNS propagation time depends on TTL (Time to Live) settings. Default TTL is typically 24-48 hours, but most DNS changes propagate to major DNS servers within a few hours. A and CNAME records usually propagate faster, while MX and NS records may take longer. Lowering TTL values can speed up propagation.

Q2: Why do different DNS servers return different results?

DNS uses a distributed caching system. Each DNS server independently caches records until their TTL expires. After modifying DNS records, servers that cached the old records won't re-query until TTL expires, so different servers may return different results. This is what "propagation" means β€” new records gradually replace cached old records worldwide.

Q3: How can I speed up DNS propagation?

1) Lower TTL to 300 seconds (5 minutes) 24-48 hours before making changes; 2) Make the DNS changes; 3) Restore TTL after confirming the new records are live. Additionally, DNS providers like Cloudflare offer near-instant propagation. This tool uses DoH APIs from Google DNS (8.8.8.8) and Cloudflare DNS (1.1.1.1).
