opAddress review
Focused IP discovery and address management for NMIS-connected network teams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
opAddress is FirstWave’s self-hosted IP address management software for network administrators, security teams, and managed service providers. It periodically scans configured subnets, discovers address usage, visualizes utilization, identifies duplicate assignments and rogue devices, and supports address reservation, release, reallocation, and editing. Historical address tracking adds context over time, while correlation with NMIS-managed devices connects IP information to network monitoring workflows. Teams managing multiple customers or overlapping address spaces can also use it for more complex security domains.
Its main strength is the FirstWave ecosystem. opAddress integrates with NMIS, opCharts, and OAE, and it can correlate discovered addresses with devices managed through NMIS. FirstWave describes the product as included in the FirstWave VM and as part of the NMIS 9 platform. Documentation also describes standalone installation and virtual-appliance deployment, giving organizations options for fitting IP management into an existing self-hosted environment. The combination of subnet planning, utilization views, conflict detection, and audit history gives network teams a focused operational view of address space.
opAddress uses contact-sales pricing, and the product is positioned within FirstWave’s broader platform rather than as a clearly separated standalone tier. That makes it a natural choice for NMIS users who want focused IP discovery, address auditing, and customer-specific space management in a self-hosted setup. Organizations seeking a broader standalone IPAM product outside the FirstWave ecosystem should compare how well their preferred platform matches these workflows, integrations, and deployment expectations.
