Question 1

How long does DNS propagation take?

Accepted Answer

DNS propagation typically takes 15 minutes to 48 hours, depending on the TTL (Time to Live) of the old record and how aggressively resolvers cache. Most changes propagate within a few hours.

Question 2

Why do different DNS resolvers show different results?

Accepted Answer

Each DNS resolver caches records independently based on the TTL. After a change, some resolvers may still serve the old cached record until it expires. This is normal during propagation.
