    Primary & Secondary DNS

    Secondary DNS ThatScales Globally

    Add DNScale alongside your existing DNS provider for redundancy, DDoS resilience, and faster resolution worldwide. No zone transfers needed — sync via API, Terraform, or DNSControl.

    Why add a secondary DNS provider?

    A single DNS provider is a single point of failure. When it goes down, your domains go dark — websites, APIs, email, everything.

    DDoS Resilience

    Anycast network absorbs attack traffic across multiple continents. No single target, no single point of failure.

    Global Performance

    Queries answered from the nearest point of presence. Sub-second BGP failover — not dependent on DNS TTL expiry.

    API-First Sync

    No AXFR/IXFR zone transfers needed. Sync via Terraform, DNSControl, or REST API — works with any primary provider.

    How it works

    Three steps to add DNScale as your secondary DNS provider.

    1

    Create your zone

    Sign up and create your DNS zone on DNScale — via the dashboard or the REST API.

    2

    Sync your records

    Use Terraform, DNSControl, or the API to push your records to DNScale alongside your primary provider.

    3

    Add nameservers

    Add DNScale nameservers to your domain's NS delegation at your registrar. Resolvers will query both providers.

    Built for reliability

    Whether you use DNScale as your primary, secondary, or both — the same enterprise-grade infrastructure powers every query.

    Anycast Network

    Multiple points of presence across Europe, North America, Asia-Pacific, Latin America, and Africa.

    Dual-AS Architecture

    Independent EU and Global networks with automatic BGP failover between them.

    Infrastructure as Code

    Terraform provider and DNSControl support for fully declarative, version-controlled DNS.

    DNSSEC

    Automated key management with per-provider signing support for multi-provider setups.

    Query Analytics

    Per-zone and per-edge traffic visibility with response latency metrics and resolver tracking.

    20+ Record Types

    A, AAAA, CNAME, MX, TXT, SRV, CAA, TLSA, SVCB, HTTPS, and more — all managed via API.

    DNScale vs traditional secondary DNS

    API-based synchronization instead of legacy zone transfers.
