The 7 Best IP Address Manager Tools for Network Teams

The best IP address manager depends on whether you need a live view of address use, a shared inventory of network plans, or centralized control of DNS and DHCP. For enterprise DDI, compare Infoblox Universal DDI, BlueCat Micetro, and EfficientIP SOLIDserver. For discovery and day-to-day monitoring, look at SolarWinds IPAM or ManageEngine OpUtils. NetBox and phpIPAM are strong open-source choices when your team can operate the platform.

This is a fit-based shortlist, not a performance ranking; verify supported integrations, deployment options, and licensing with each vendor.

What an IP address manager should do

IP address management (IPAM) gives a team a dependable record of address space: networks, subnets, assigned or reserved addresses, ownership, and capacity. It helps prevent duplicate allocations and plan new networks. For example, 10.20.4.0/24 is a defined address block; IPAM records its purpose and status.

Some tools mainly inventory and scan address space. Others are part of DDI, the combination of DNS, DHCP, and IPAM. DHCP leases addresses to clients; DNS maps names to addresses. A DDI product may coordinate those services directly or provide one control layer over existing servers. That distinction matters: a static inventory can document a DHCP scope without actually configuring the DHCP server.

Seven IP address manager tools to consider

1. SolarWinds IP Address Manager — discovery and monitoring

SolarWinds positions IPAM within its Observability Self-Hosted portfolio. The product page lists automated discovery across on-premises and cloud environments, conflict resolution, alerts, reports, and DHCP/DNS management. It suits teams that want IP tracking alongside broader infrastructure monitoring. SolarWinds lists a 30-day trial and provides quotes on request. See SolarWinds IP Address Manager.

2. ManageEngine OpUtils — subnet scans and network utilities

OpUtils combines IPAM with tools such as switch-port mapping. It can scan subnets on demand or on a schedule, reserve addresses, track allocation history, report availability, and handle IP requests. ManageEngine also documents Microsoft DHCP scope monitoring. Consider it for address tracking and switch visibility in one tool. Review OpUtils IP Address Manager features.

3. Infoblox Universal DDI — centralized hybrid-network services

Universal DDI provides a cloud-based control plane for DNS, DHCP, and IPAM across hybrid and multicloud environments. It suits organizations that need consistent DDI workflows across many locations and cloud services. It is subscription-based; list the services and sites you need before requesting a quote. See Infoblox Universal DDI Management.

4. BlueCat Micetro — an overlay for existing DDI

Micetro centralizes DNS, DHCP, and IPAM across on-premises, cloud, and branch environments. BlueCat describes it as an API-driven overlay for existing infrastructure, making it a candidate when you want unified control without replacing DNS or DHCP services. Check compatibility with your servers and clouds. See BlueCat Micetro.

5. EfficientIP SOLIDserver — integrated DDI appliances

SOLIDserver is an integrated DNS-DHCP-IPAM platform offered as appliances. EfficientIP documents IPv4/IPv6 planning, VLAN/VXLAN management, multi-vendor DNS and DHCP, cloud visibility, and automation. Evaluate it when DDI coordination and policy-driven workflows are priorities. See the SOLIDserver DDI product page.

6. NetBox — network source of truth and automation

NetBox is an open-source network documentation platform with IPv4/IPv6 IPAM, prefixes, ranges, and VRFs, alongside devices and other infrastructure objects. It fits teams modeling intended network state and feeding automation through APIs and extensions. It is an inventory to maintain and integrate: documenting a range does not itself configure an external DHCP server or guarantee live discovery. See NetBox IPAM documentation.

7. phpIPAM — self-hosted open-source IPAM

phpIPAM is a free, open-source web app focused on IP management. Its features include IPv4/IPv6 subnets, free-space and status views, scanning, VLANs, VRFs, group permissions, a REST API, and PowerDNS integration. It suits teams seeking dedicated IPAM without commercial licensing, provided they can maintain the app, database, backups, and upgrades. Check the phpIPAM feature list.

How to choose the right IPAM tool

• Need active discovery and alerts? Compare SolarWinds and OpUtils, then test how scans treat firewalled, sleeping, or intermittently connected devices.
• Need DNS and DHCP operations in one place? Compare Infoblox, Micetro, and SOLIDserver against your existing vendors, cloud services, failover needs, and change workflows.
• Need a network inventory for people and automation? Evaluate NetBox’s data model, permissions, API, and integration requirements.
• Need a no-license-cost self-hosted option? Compare phpIPAM with your team’s ability to run and secure it over time.

Before migrating a spreadsheet, verify that the tool can represent your IPv4 and IPv6 plan, overlapping address spaces or VRFs, reservations, custom metadata, roles, audit history, imports, and backups. Confirm which integrations write changes and which only read or display data. Run a pilot on one subnet, compare the scan against DHCP leases and device records, and test how quickly a conflict or mistaken reservation can be corrected. These checks reveal whether a tool fits your network operations, not just its feature list.
