Declarative IPAM and DNS Lifecycle Automation in Hybrid Environments Using Infoblox NIOS and Terraform

Abstract

The rapid adoption of hybrid cloud infrastructures exposed critical gaps in IP Address Management (IPAM), DNS, and DHCP (DDI) automation. Enterprises struggled with fragmented tools, manual workflows, and inconsistent configurations across cloud (AWS, Azure) and on-premises environments, leading to operational inefficiencies and compliance risks. This paper presents a declarative, code-driven framework leveraging Infoblox NIOS and Terraform to automate DDI lifecycle management. By adopting Infrastructure-as-Code (IaC) principles, the framework ensures idempotent provisioning, drift detection, and policy compliance. Validation tests demonstrate a 70% reduction in provisioning latency and 85% fewer configuration errors, with scalability supporting over 10,000 IP allocations and sub-100ms DNS propagation.
