Secondary DNS ThatScales Globally
Add DNScale alongside your existing DNS provider for redundancy, DDoS resilience, and faster resolution worldwide. No zone transfers needed ā 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 ā 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 ā not dependent on DNS TTL expiry.
API-First Sync
No AXFR/IXFR zone transfers needed. Sync via Terraform, DNSControl, or REST API ā works with any primary provider.
How it works
Three steps to add DNScale as your secondary DNS provider.
Create your zone
Sign up and create your DNS zone on DNScale ā via the dashboard or the REST API.
Sync your records
Use Terraform, DNSControl, or the API to push your records to DNScale alongside your primary provider.
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 ā 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 ā all managed via API.
DNScale vs traditional secondary DNS
API-based synchronization instead of legacy zone transfers.
| Feature | Traditional (AXFR) | DNScale |
|---|---|---|
| Sync method | Zone transfer (AXFR/IXFR) | API / Terraform / DNSControl |
| Setup | TSIG keys, firewall rules, SOA tuning | API key + declarative config file |
| Works with any primary | Only if primary supports AXFR | Yes ā any provider with an API |
| Propagation | Pull-based (SOA refresh interval) | Push-based (immediate on deploy) |
| Automation | Custom scripts or manual | CI/CD native with drift detection |
| Global anycast | Varies by provider | Multiple POPs, dual-AS |
| Record types | Limited by transfer | Full support for 20+ types |
| Version control | Not inherently supported | Records defined in Git |
Works with any primary provider
DNScale syncs via API ā no zone transfer support required from your primary provider.
