DNS Management Service

We host your authoritative DNS on geographically distributed nameservers with anycast routing. DNS queries are answered by the nearest server, minimizing resolution latency worldwide. Our DNS infrastructure is designed for high availability — individual server failures are invisible to clients because queries are automatically routed to healthy servers.

Zone management is automated through our DNS API and integrated with your infrastructure-as-code pipeline. DNS records are version-controlled alongside your server configurations. When you provision a new server, the corresponding DNS records are created automatically. When you decommission a server, stale records are cleaned up. No more orphaned DNS entries pointing to servers that no longer exist.

DNSSEC protects your domains from cache poisoning and man-in-the-middle attacks by cryptographically signing DNS responses. We manage the complete DNSSEC lifecycle — key generation, zone signing, DS record publication, key rotation, and algorithm upgrades. Key rollovers follow RFC best practices to prevent resolution failures during transitions.

DNSSEC monitoring verifies that signatures are valid, keys are not approaching expiration, and the chain of trust from root to your zone is intact. Signature expiration is a common DNSSEC failure mode, and our automation re-signs zones well before signatures expire. You get the security benefits of DNSSEC without the operational complexity.

DNS-based failover automatically redirects traffic when your primary server becomes unreachable. Health checks monitor your endpoints, and when a failure is detected, DNS responses are updated to point to your standby server within the TTL window. For critical services, we configure low TTLs to minimize failover time.

Geographic routing directs users to the nearest server based on their DNS resolver location. Weighted routing distributes traffic across multiple endpoints according to configurable ratios — useful for gradual migrations or A/B testing. Latency-based routing sends users to the endpoint with the lowest measured network latency. These routing policies are managed through the same automation pipeline as your standard DNS records.

We implement DNS security best practices including response rate limiting to mitigate DNS amplification attacks, query logging for forensic analysis, and access controls that restrict zone modification to authorized personnel. Registrar accounts are secured with two-factor authentication and registrar lock to prevent unauthorized domain transfers.

DNS change auditing logs every record modification with who made the change, what was changed, and when. This audit trail is essential for troubleshooting resolution issues and meeting compliance requirements. Monthly DNS health reports verify zone configuration correctness, DNSSEC validity, and nameserver responsiveness across all geographic locations.
