applicationdnsjson

applicationdnsjson is a JSON-based configuration format used to declare DNS records and related routing behavior for software applications. It is designed to be consumed by automation tools during deployment to provision and manage domain entries in cloud or on-premises DNS services. The format is not tied to a single provider and emphasizes machine readability and reproducibility.

A typical applicationdnsjson document defines a target domain and a set of DNS records, along with optional routing and health-check metadata. Common fields include domain, records (an array of record objects with type, name, value, and ttl), and routing (policy, healthCheck). Some implementations also support metadata, versioning, and environment-specific overrides.

Usage generally involves storing the file in a repository, validating it with a linter or schema, and applying changes through a DNS provisioner or platform API. Tools may support multi-provider outputs, diff-based updates, and rollback hooks. Example: { "domain":"example.com","records":[{"type":"A","name":"www","value":"203.0.113.10","ttl":300}],"routing":{"policy":"round_robin"} }

Because applicationdnsjson is not part of a formal standard, behavior varies by tool. Users should secure API credentials, manage version-controlled state, and be mindful of conflicts with existing DNS records. The format is commonly used in cloud-native environments alongside other infrastructure-as-code practices.
