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 as a secondary zone and complete zone transfers.
• Configure each DNS provider as a primary zone, and use APIs to update zones on each provider.
• Configure each DNS provider as a primary zone, and use a third-party tool to administer each zone.
• Use a different DNS provider as primary zone, and configure Edge DNS as a secondary zone.
• Use outbound zone transfers to transfer zone data from ​​Edge DNS servers to your external name servers. For more information, see Enable outbound zone transfers.
