Cloudflare Internal DNS Now Generally Available, Unifying Enterprise DNS Infrastructure
Key Takeaways
- ▸Consolidates public, private, and cloud DNS operations onto one platform with unified policies and a single audit trail
- ▸Eliminates split-horizon DNS complexity and drift by treating internal/external resolution as separate views over shared zones
- ▸Extends Zero Trust security to DNS by enforcing resolver policies through Cloudflare Gateway alongside other traffic controls
Summary
Cloudflare announced the general availability of Internal DNS, a private DNS service that consolidates public and private DNS management on a single platform. The service runs on Cloudflare's global network and control plane, eliminating the traditional split between separate DNS systems for internal resources, public DNS, and cloud-specific resolvers.
Enterprises typically manage DNS across multiple platforms—public DNS, internal DNS, and cloud-native DNS services in different cloud environments—each with separate security policies and no shared control plane. This fragmentation creates operational complexity and drift issues, particularly with split-horizon DNS setups that must remain synchronized to prevent outages. Cloudflare Internal DNS solves this by unifying all DNS operations into a single control plane with consistent policies, audit trails, and management interfaces.
The service comprises two components: Gateway Resolver for recursive resolution and policy enforcement, and Internal Authoritative DNS for managing private zones. Customers define Internal Zones for private resources, DNS Views to segment which users see which records, and Resolver Policies to route queries based on flexible rules. Zone references enable reuse of shared zones across multiple views, eliminating duplicated configurations. For Enterprise customers, Internal DNS is included with Cloudflare Gateway at no additional cost.
- Replaces legacy DNS hardware appliances with cloud-native infrastructure powered by Cloudflare's 1.1.1.1 resolver network
- Included at no cost for Cloudflare Enterprise customers as part of Cloudflare Gateway
Editorial Opinion
Internal DNS has historically been the weak link in enterprise infrastructure—fragmented across incompatible platforms and difficult to secure consistently. Cloudflare's move to unify it with public DNS and Zero Trust controls on a single global platform addresses a genuine operational pain point. Success will depend on execution of complex features like split-horizon DNS and maintaining the performance and reliability enterprises expect, but this represents a meaningful step toward simplifying enterprise networking.
