Is this causing a performance hit on my data? >What should a normal TTL be? 24 hours is the default for the Minimum field. The TTL field in the Domain Information dialog only actually affects the caching of the other data in the dialog. Minimum is the default TTL for any record that doesn't have an explicit TTL. This is the value you want to manipulate. >I also noticed that the Expires is set at 302400 which is 84 hours. >Not sure where this number came from or if it was the default.

No. The Expire entry is the length of time a secondary server will continue to serve the domain after losing contact with the primary server. The default value is 604800, or 1 week. You have it set to half that, 3 1/2 days. ____________________________________________________________________ Chris Buxton cbuxton@menandmice.com Men & Mice http://www.menandmice.com Makers of: QuickDNS Pro
