03DNS Architecture

The control plane starts with a name.

Design domain systems for clarity, continuity, and accountable change across every environment.

A

Resolve

Map services and endpoints through deliberate record architecture.

B

Control

Define ownership, access, and safe change procedures.

C

Observe

Maintain visibility over health, expiry, and configuration drift.

DNS control model

AUTHORITATIVE / RESOLVER / LIFECYCLE
01Zone design

Authority, delegation, naming conventions, and environment boundaries structured for clear ownership and review.

02Record lifecycle

Creation, validation, TTL planning, approval, rollback, and retirement handled through repeatable change procedures.

03Integrity

DNSSEC readiness, registrar controls, certificate dependencies, and access boundaries evaluated as one trust chain.

04Visibility

Resolution health, expiry, propagation, stale records, and configuration drift surfaced before they become incidents.

Operational coverage

AUTHORITY

Authoritative architecture

Zone hierarchy, delegation, provider topology, and failover designed around real service dependencies.

ROUTING

Traffic control

TTL, weighted answers, geographic policy, and health-aware routing used deliberately and documented clearly.

GOVERNANCE

Domain governance

Registrars, renewals, contacts, access, and audit trails managed as part of infrastructure—not administration.

Record architecture

Services and endpoints are mapped through a deliberate record structure, so the shape of the system can be read from its names.

Ownership and change

Access, approval, and rollback paths are defined before changes are made, keeping the most sensitive layer of routing under control.

Visibility

Health, expiry, and configuration drift are monitored continuously rather than discovered during an outage.
