Carrier-Grade Recursive DNS for ISPs and Telcos

Why DnsMARA Instead of Other Commercial Solutions

• Resolver-first design

  Focuses on accelerating recursive DNS, improving cache efficiency — get the performance and capabilities that truly matter for an ISP.

• Operator-first design

  Anycast, failover safety, and rolling upgrades are built in.

• Performance-first roadmap

  Zero latency cache, prefetch, DoH/DoT scale, not DDI feature catch-up.

• Transparent capacity-based licensing

  Aligned to subscriber growth.

• POC-driven buying

  Measurable exit criteria on latency, headroom, and resilience.

• No need for load balancers

  Simpler, cheaper, more reliable architecture.

Why DIY Open-Source DNS Fails for ISPs

• Threat intelligence you can’t DIY

  Blocking malware and C&C domains requires curated RPZ feeds and safe, fast distribution. Maintaining those lists alone is unrealistic for a single ISP; we run this at scale every day.

• Performance and Quality of Experience

  Legacy open source resolvers cannot deliver the performance density and low latency required for ISP deployments. Query latency rises resulting in slow page loads and bad user experience.

• HA + anycast + encrypted DNS are non-trivial at scale

  Clustering, failover, anycast catchment and DoT/DoH overhead need careful engineering and optimization to avoid latency spikes and instability.

• Operational visibility and abuse control

  Useful dashboards, statistics, reports, subscriber infection detection, and RPZ analytics don’t come for free - you'll build and maintain them yourself (and then support them during incidents).

• No safety net with DIY

  In a resolver incident (misconfig, DDoS, route shift), DIY means no vendor SLO or hotfix path. History shows DNS failures can have outsized impact.

• DNS is a critical service — Not a place to experiment

  One outage or blacklisting incident can erase years of “labor savings“. DnsMARA is a turnkey, high-performance DNS resolver designed specifically for ISPs, with a proven track record across leading networks worldwide.

Why a Local Recursive DNS (Not Public Cloud Resolvers)

• Lower latency, instantly faster

  Keep lookups inside your network for sub-millisecond responses. Pages open quicker, apps feel snappier, and streaming starts without hesitation.

• Correct CDN routing, better experience

  Your resolver points subscribers to the nearest CDN edge — every time. That means smoother video, fewer stalls, and consistently high quality.

• Cost control, not surprise transit

  Local recursion and caching keep traffic on-net and off expensive international links. Avoid wrong-region routing that inflates transit bills and wrecks margins.

• Full control, security, and insight

  Enforce your policies (RPZ), block malware, and spot infected lines before they harm your reputation. Offer DoT/DoH locally to keep users — and analytics — on your network.

DNS Security for ISPs and Telcos

Protect your network, your subscribers, and your reputation

• Keep Control with Encrypted DNS

  Support DNS over TLS and DNS over HTTPS without losing insight or policy control. DnsMARA lets subscribers use encrypted DNS on your infrastructure — not on public resolvers like Google or Cloudflare — preserving analytics, compliance, and customer trust.

• Block Malware Before It Spreads

  Stop infections where they start. DnsMARA uses RPZ-based blocking and real-time threat feeds to prevent access to malware, phishing, and command-and-control domains — cutting off attacks before they reach your network.

• Detect and Clean Infected Subscribers

  Built-in detection tools reveal devices repeatedly querying malicious domains. Your abuse teams can take proactive action before infections damage network reputation or lead to IP blacklisting.

• Secure DNS Integrity with DNSSEC

  DNSSEC verifies every DNS response using cryptographic signatures. DnsMARA performs full validation, protecting against forged responses, cache poisoning, and redirection attacks.

• Resilient Against DDoS and Abuse

  Intelligent rate-limiting, query shaping, and Anycast clustering protect against amplification and flood attacks. Even during high traffic spikes, service remains stable and responsive.

• Built-In Hardening and Secure Operations

  Signed updates, a hardened OS base, role-based access control, and detailed audit trails protect both the system and its administrators — ensuring compliance and operational confidence for ISP-grade environments.

Platform Deployment Options

Choose from different platform and installation options for running DnsMARA.

• Dedicated hardware appliance

  Fully tested, optimized, factory-tuned, ready to run.

• Bare metal on your hardware

  Install from certified profiles & images on your own hardware.

• Virtual appliance
