What does DNS propagation mean?

When you change DNS records, the new values must spread across all global DNS resolvers. This process is called propagation and can take up to 48 hours depending on the TTL (Time to Live) value.

Which resolvers are checked?

Google (8.8.8.8), Cloudflare (1.1.1.1), Quad9 (9.9.9.9), OpenDNS (208.67.222.222), Verisign (64.6.64.6), and the server's local resolver.

What does "NXDOMAIN" mean?

NXDOMAIN (Non-Existent Domain) means the resolver has no record of the domain at all — it either does not exist or has not yet propagated to that resolver.

How long does DNS propagation take?

Changes typically propagate within 1–2 hours for most resolvers, but can take up to 48 hours in rare cases. Lower TTL values speed up propagation.

What is a TXT record used for?

TXT records store arbitrary text data. They are commonly used for domain ownership verification (Google Search Console, Amazon SES) and email authentication (SPF, DKIM).
