What is DNS propagation?

DNS propagation is the delay before a DNS change is seen everywhere.

Last updated November 9, 2026

The short version

DNS propagation is the delay before a DNS change is seen everywhere. Resolvers cache records for as long as the record's TTL says, so old answers can remain until it expires. Lowering the TTL before a planned change shortens the wait. Checking with dig shows what your resolver currently sees.
