InterMapper's timer for updating each device's DNS is tied to the TTL of the associated DNS record on your DNS server (min. 2 minutes, max 24 hours).

If the TTL is low enough, reprobing the device or using a sub-minute poll interval can make the DNS update appear nearly instantaneous.

Check the time-to-live setting on your DNS servers, and see whether that matches the update period you're seeing?
