Multiprovider DNS support

Edge DNS is architected for availability, resilience, and performance. As such, it addresses redundancy concerns that might lead to interest in multiprovider authoritative DNS. Each ​Akamai​ name server cloud is backed by thousands of globally distributed servers, and each Edge DNS customer is assigned a unique set of ​Akamai​ name server delegations.

For customers who want to use multiple authoritative DNS providers, consider the following options:

• Configure a hidden primary name server at the customer origin, and set up each DNS provider to operate in secondary mode and complete zone transfers.
• Configure each DNS provider in primary mode, and use APIs to update zones on each provider.
• Configure each DNS provider in primary mode, and use a third-party tool to administer the zone.
• Use a different DNS provider as primary, and configure Edge DNS in secondary mode.

Edge DNS does not support zone transfers to other DNS providers. Using a multiprovider DNS strategy is incompatible with Edge DNS features such as sign-and-serve DNSSEC, zone apex mapping, top-level CNAME, and alias zones.
