With DNS Prefresh enabled, the edge servers refresh your origin DNS record independent from receiving a request from end-users, and prior to the expiration of your origin DNS resolution's TTL.
Contact Akamai Professional Services for help configuring this behavior.
The DNS name might fail to prefresh, as there is a limit on the number of prefreshes the Akamai server can perform per second. This limit might be reached due to the large number of names the server is trying to maintain (origins, maps, etc.).
What it does
Enables or disables the behavior.
Set the delay before initiating an asynchronous refresh of the DNS resolution.
Set the timeout for prefreshing the DNS entries if there have been no requests to that domain name.
