The default value of the refresh interval for a DNS record is 7 days.
Key Takeaway: All dynamically registered resource records are tagged with a timestamp to track the age of the record. This is called Aging. Scavenging is the process of deleting outdated resource records on which time stamps have been placed. The refresh interval is the time after the no-refresh interval during which timestamp refreshes are accepted and resource records are not scavenged.
