Frequently Asked Questions
DNS propagation is the time until a record change (such as a new hosting IP) is visible across the internet. The change applies to your nameservers instantly; what you wait for is other resolvers holding the old cache until its TTL expires.
It depends on the old record TTL. A TTL of 300 means about 5 minutes at most, while 86400 can take up to 24 hours. Nameserver changes at the registrar can take 24–48 hours. Tip: lower the TTL a day before moving hosting.
Each resolver keeps its own cache. A resolver that looked up the record before your change keeps the old value until the TTL expires. The TTL left column shows when that cache expires.
