Once a primary Enhanced DNS zone is provisioned in Akamai Luna Control Center, a nonbrowser-based client may invoke this API to manage the DNS records of the Zone. It is a unique value calculated for every zone configuration, and must be presented with the Zone submission, which is used by Luna to guarantee that the submission modifies the current configuration.
This is to prevent inadvertently overwriting another client’s submission.
So the serial number from my post today would be 2011031900.Maintaining single global SOA serial for all servers was found as hard problem.Attributes like can't be used because they can go back in time (because of replication).Without DNS, that website you've worked so hard on would be completely invisible.(Although it's possible to access some sites using only the IP address of their web server, this is not the case for virtual websites, which require that their hostname be included in the HTTP request header.
