# Overview

> Gcore Managed DNS is an authoritative DNS service with Anycast routing, dynamic responses, healthchecks, DNSSEC, and CDN integration.

Gcore Managed DNS is an authoritative DNS service for domain delegation. Domain records are managed through the [Gcore Customer Portal](https://portal.gcore.com), [REST API](/api-reference/dns), or [Terraform](/dns/dns-plugins/manage-dns-with-terraform-v2), and queries are served through Gcore's global AnycastDNS network, routing end users to the nearest edge location automatically.

[Dynamic response](/dns/dns-records/configure-weight-balancing-and-geobalancing) delivers different records to different clients based on geolocation, ASN, subnet, or weight, including EDNS Client Subnet support for routing accuracy.

[Healthchecks](/dns/dns-failover/configure-and-use-dns-failover) monitor server availability and remove failing IPs from DNS responses, redirecting traffic to working endpoints automatically.

[DNSSEC](/dns/getting-started-with-dnssec) validates DNS responses with digital signatures, protecting against cache poisoning and DNS spoofing.

[CDN integration](/dns/dns-records/advanced-managing/cdn-integration) resolves A and AAAA records to CDN addresses directly, eliminating the CNAME lookup step.

[CNAME flattening](/dns/dns-records/specify-cname-at-root) enables CNAME-like behavior at the zone apex where standard CNAME records are not permitted. [HTTPS records](/dns/dns-records/what-is-an-https-record-and-how-is-it-configured) carry connection parameters for HTTPS services in DNS responses, and IPv6 is supported via AAAA records.

[OctoDNS](/dns/dns-plugins/use-gcore-dns-as-a-secondary-dns-with-octodns), [Certbot](/dns/dns-plugins/get-a-let-s-encrypt-certificate-with-certbot), and [Terraform](/dns/dns-plugins/manage-dns-with-terraform-v2) integrations cover GitOps-style zone management, certificate automation, and infrastructure-as-code workflows.

[Grafana](/dns/grafana/view-dns-statistics-in-grafana) shows DNS request counts in the Gcore data source.

DNS records are managed in two modes. **Non-advanced** mode is for standard DNS entries — one value per record, no traffic routing. **Advanced** mode supports RRsets with multiple values and enables dynamic response, Healthchecks, and geo-routing rules.
