Question 1

How long does DNS propagation take?

Accepted Answer

DNS propagation typically takes 1 to 48 hours. Most resolvers update within 1 to 4 hours, but TTL settings and ISP caching can extend this up to 48 hours in rare cases.

Question 2

Why do some resolvers show old DNS records?

Accepted Answer

DNS resolvers cache records for the duration of the TTL (Time To Live) set on the record. Until that cache expires, the resolver will return the old value even after you update your DNS.

Question 3

How do I check if my DNS has propagated?

Accepted Answer

Enter your domain name in DomainSpy's propagation checker. It queries 12 global resolvers simultaneously and shows which ones have your new records, along with per-resolver latency.
