As telecom networks evolve toward cloud-native, automated, and converged environments, the need for a next-generation DNS solution has become more critical than ever. Enter Titan.ium’s Infrastructure Domain Name System (iDNS) — a fully cloud-native, telecom-grade DNS that transforms how operators manage, scale, and secure their networks.
From enabling 5G use cases like SEPP discovery to delivering ultra-low latency, high reliability, and deep automation, iDNS is purpose-built to meet and exceed the performance and security expectations of today’s mobile network operators (MNOs), fixed-line carriers, and converged service providers.
Why Telecom Operators Need iDNS Now
Traditional DNS servers were built for the static internet era. Telecom operators today are grappling with:
- Higher throughput demands during peak hours
- DNS resolution across dynamic cloud-based endpoints
- Split traffic across private and public networks
- Need for automated updates, fault tolerance, and rapid rollout
Titan.ium iDNS addresses all these challenges — and goes further.
Cloud-Native DNS Designed for Scale and Resilience
Built on Microservices
Unlike monolithic DNS platforms, iDNS is container-based and microservices-driven. This enables:
- Independent upgrades of components
- Fault isolation and faster recovery
- Seamless feature rollouts without service disruption
Rapid Deployment in Cloud Infrastructure
Deploy iDNS exclusively in a cloud or alongside other Titan.ium network functions like 5G SEPP for secure roaming. Supports:
- Public and private clouds
- Hybrid infrastructure
- Edge deployments
DevOps-Ready and Scalable
Integrates with CI/CD pipelines for automated provisioning, deployment validation, and service rollout — ideal for agile network operations.
Advanced Telecom DNS Features That Matter
Authoritative and Recursive DNS Modes
Supports authoritative zones, recursion with referral following, and full caching — all RFC-compliant and optimized for telecom-grade DNS query volumes.
Split-Horizon DNS – and Beyond
iDNS delivers traditional split-horizon functionality (based on source IP/subnet) and extends it with split-view based on destination IP and port — empowering differentiated routing in complex topologies.
Zone Chaining for TLDs
A unique feature that allows resolution against multiple zones under the same top-level domain. Useful for operators managing different sub-networks under a shared namespace.
Endpoint Monitoring & Glue Records
Dynamically checks availability of glue records (A/AAAA) before inclusion, improving query reliability and DNS hygiene.
Security-First DNS
Includes built-in protections:
- DNS overload mitigation
- Recursion access control
- NSID support for name server identification
- Automated certificate and trust management
Smart Provisioning with Titan.ium Datastores
Zones and resource records can be managed via REST APIs, allowing bulk provisioning and fine-grained delegation through isolated admin tables.
Standards Compliant and 5G-Ready
Titan.ium iDNS is fully compliant with:
- IETF RFCs for DNS standards
- GSMA recommendations, including support for 5G Security Edge Protection Proxy (SEPP) discovery — a cornerstone for secure 5G roaming
This makes it the ideal DNS solution for MNOs building cloud-native, secure, high-performance 5G environments.
A Foundation for Network Transformation
More than a feature-rich DNS, iDNS represents a strategic leap in how operators approach DNS infrastructure. Key transformational benefits include:
- Automated delivery, scaling, and upgrades
- Operational simplification across mobile, fixed, and converged networks
- Future-ready architecture aligned with network slicing, edge compute, and secure interconnects
- Improved agility for launching services and responding to network conditions
“The iDNS is not just addressing today’s network demands; it’s establishing a future-proof foundation for digital transformation.”
