The DNS cache doesn’t ever flush, unless you explicitly tell it to or you make a DNS/networking related configuration change.

Time To Live, or TTL for short, is the sort of expiration date that is put on a DNS record. The TTL serves to tell the recursive server or local resolver how long it should keep said record in its cache. The longer the TTL, the longer the resolver holds that information in its cache.

How often do DNS servers replicate?
