Enterprise Core Network Service

Integrate DNS, DHCP, and IPAM into one intelligent, automated DDI platform

SmartDDI Overview

In today’s fast-moving digital era, connectivity has become the backbone of enterprise operations, while DNS and IP serve as the foundation of every network. DDI—which combines DNS, DHCP, and IP Address Management (IPAM)—forms the core of the network service layer, bridging applications and infrastructure to enable smooth communication and coordination across devices, systems, and users.

Yamu SmartDDI is a next-generation infrastructure platform designed for modern enterprise networks. By deeply integrating DNS, DHCP, and IPAM, it enables intelligent synchronization and automation of network information. SmartDDI helps organizations enhance automation, strengthen security and visibility, simplify daily operations, and maintain consistency across multi-cloud, hybrid, and large-scale distributed environments.

As digital transformation accelerates, DDI has become a critical part of IT infrastructure across all industries. Yet, traditional network management still struggles with manual maintenance, high operational costs, inconsistent configurations across data centers and clouds, and weak security and compliance control. SmartDDI was built to address these challenges. Through centralized resource management and policy control, it enables enterprises to build a secure, efficient, visible, and well-governed network foundation, supporting continuous innovation and sustainable digital growth. It is particularly suited for organizations managing complex, large-scale networks, pursuing operational automation and compliance, or undergoing digital transformation.

Key Benefits

  • 1.Ensuring Business Continuity with Highly Available Infrastructure

    SmartDDI offers comprehensive monitoring through multiple probing protocols to track the real-time status of core services. With flexible detection strategies and intelligent scheduling algorithms, it provides seamless failover and smart traffic distribution to minimize service interruption. The result is a stable, reliable infrastructure that ensures the continuous availability of mission-critical business systems.

  • 2.Enabling Agile Operations and Accelerated Resource Delivery

    SmartDDI integrates with open APIs, CI/CD pipelines, and ITSM platforms to automate IP allocation and DNS registration. It supports dynamic registration for short-lifecycle workloads such as containers and microservices, with real-time monitoring and intelligent alerts—helping IT teams achieve rapid, automated resource delivery within minutes or even seconds.

  • 3.Strengthening Security and Compliance for Core Network Stability

    Built with carrier-grade, kernel-level security acceleration, SmartDDI delivers high-performance protection for DNS and DHCP services, maintaining reliability under heavy load or attack conditions. Through distributed deployment and local caching, SmartDDI ensures uninterrupted DNS services at edge nodes even during network failures, maintaining high service availability. Its built-in DNS firewall and intelligent threat detection engine can identify and block malicious traffic at early stages, enabling zero-trust policy enforcement and real-time compliance auditing across the network.

  • 4.Optimizing Resource Governance and Improving Operational Efficiency

    With an integrated DDI management platform, SmartDDI provides centralized visualization, policy-based allocation, and intelligent governance of IPv4 and IPv6 resources. It automatically associates addresses, users, and services, supporting fast fault localization and traceability to greatly reduce troubleshooting time. Combined with its policy engine and automation orchestration, SmartDDI helps optimize resource utilization and O&M efficiency. Through seamless integration with cloud platforms, security systems, and IT management tools, it drives smarter, more refined network operations.

  • 5.Enabling Smooth IPv6 Migration and Non-Disruptive Transition

    SmartDDI is fully compatible with both IPv4 and IPv6, supporting automated allocation and transition strategies in dual-stack environments. It ensures seamless, disruption-free business switching during IPv6 migration while maintaining full resource consistency, providing a reliable foundation for long-term network evolution.
