Oracle Cloud Infrastructure DNS

What Oracle Cloud Infrastructure DNS is

Oracle Cloud Infrastructure DNS manages DNS zones and records, then handles domain queries through Oracle Cloud Infrastructure’s edge network. It supports publicly reachable zones and private hostname resolution for applications within or between virtual cloud networks. Primary authoritative zones and secondary zones are available for redundancy. Traffic Management can direct public queries according to endpoint health, geographic location, ASN, or originating IP prefix; policies can use equal or custom weights and switch to secondary answers when a primary is unhealthy. The service is accessible through the browser-based Console, REST API, OCI CLI, and SDKs, with Oracle Cloud Infrastructure IAM governing access. DNSSEC can cryptographically authenticate lookup responses on public zones, but it does not encrypt responses and is not supported on private zones. OCI DNS requires a paid OCI account under a pay-as-you-go or Universal Credits contract, and has no free plan. The listed rate is priced on request, billed per 1,000,000 queries; the detailed listed price is $1.11401 per 1,000,000 queries. Limits include 1,000 zones per account, 25,000 records per zone, and 1 MB per zone file.

Who it suits

OCI DNS suits teams managing public or private DNS for applications on Oracle Cloud Infrastructure, including those needing traffic steering or secondary zones. Its API, CLI, Console, and SDK access support different management workflows.

Limits

An account supports up to 1,000 zones, each zone supports 25,000 records, and zone-file uploads are limited to 1 MB. Traffic Management allows 100 policies and 1,000 attachments per tenant; public DNS zones are supported only in the OC1 commercial realm.

Getting started

1. Create a paid OCI account under pay-as-you-go or Universal Credits
2. Open the OCI Console or use the REST API, OCI CLI, or SDK
3. Authenticate through Oracle Cloud Infrastructure IAM
4. Create public or private DNS zones and records
5. Configure primary or secondary DNS as needed
6. Set traffic-steering policies and health checks for public DNS

Verdict

OCI DNS provides zone management, traffic steering, and multiple administration interfaces, with defined account and capacity limits. Review the private-zone DNSSEC exclusion and public-only Traffic Management scope if those capabilities matter.
