# Overview

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.

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.

## Public DNS

[Public DNS](https://gcore.com/public-dns) provides free recursive DNS resolvers as an alternative to provider-supplied resolvers, improving resolution speed and protecting against DNS substitution attacks.
