Best IPAM Software Compared: 8 IP Address Management Tools by Architecture, DNS/DHCP Support and Fit

IP address management (IPAM) software tracks which addresses, subnets and VLANs exist, who or what holds each one, and how DNS and DHCP records map to them. Spreadsheets break down once a network passes a few hundred devices, because duplicate assignments, stale reservations and shadow devices quietly cause outages and audit findings.

This comparison covers eight IPAM tools across enterprise DDI suites, monitoring-suite add-ons, and open source options. It focuses on how each product is built and what it integrates with, rather than on list prices, which change often and are usually quote-based. Confirm current pricing with each vendor. The wider context for choosing a tool is in our IPAM buying guide and the Network Monitoring Software category lists monitoring platforms that often include IPAM modules.

Two standards frame what any IPAM tool must handle: private address planning under RFC 1918 and IPv6 addressing under RFC 4291.

How we compared IPAM tools

We compared tools on architecture, DNS and DHCP integration, discovery, API access and operating model. SaaSPodium does not yet hold ratings for most IPAM vendors, so this article avoids invented scores and describes documented product design instead.

• Architecture: a full DDI suite runs the DNS and DHCP services itself, while a monitoring-suite module reads from existing servers.
• Discovery: how the tool finds live and rogue addresses through ping sweeps, SNMP and ARP tables, or DHCP lease data.
• Integration: APIs, Active Directory, cloud inventory and ticketing connectors.
• Operating cost: licenses, appliances and the admin time to keep data accurate.

1. Infoblox

Infoblox is an enterprise DDI platform that combines DNS, DHCP and IPAM in one managed system. It is typically chosen when an organization wants one authoritative source for core network services across data centers, branches and cloud.

• Architecture: grid-based design where members share one database and are managed centrally, deployed as appliances, virtual machines or cloud services.
• Fit: large enterprises that want DNS and DHCP run by the same product that tracks addresses.
• Trade-off: replacing existing DNS and DHCP servers is a larger project than adding a read-only IPAM module. Visit the official site at Infoblox for current editions.

2. BlueCat Address Manager

BlueCat Address Manager is a centralized IPAM and DNS/DHCP management product built for large and regulated environments. It places an authoritative address database in front of DNS and DHCP services and exposes automation interfaces for integrations.

• Architecture: a central management layer with managed DNS and DHCP servers, available as appliance, virtual and cloud deployments.
• Fit: financial services, healthcare and public sector teams that need strict change control and audit trails.
• Trade-off: capable but sized for larger programs, so small teams may find it more than they need.

3. EfficientIP SOLIDserver

EfficientIP SOLIDserver is another DDI suite that unifies IPAM with DNS and DHCP, aimed at enterprises and service providers. It is a credible alternative to the two market leaders when a team wants a competitive bid.

• Architecture: appliances and virtual editions with central IPAM and managed DNS/DHCP services.
• Fit: organizations that need DNS security features alongside address management.
• Trade-off: smaller community and fewer third-party guides than the largest vendors.

4. SolarWinds IP Address Manager

SolarWinds IP Address Manager is an IPAM module in the Orion platform that tracks addresses and works with existing DHCP and DNS servers. Teams already using SolarWinds monitoring get one console for address, device and performance data.

• Architecture: self-hosted on Windows, tied to the Orion database and polling engines.
• Fit: mid-sized IT teams that want multi-vendor DHCP and DNS visibility without replacing those servers.
• Related: see SolarWinds Network Performance Monitor on SaaSPodium for the monitoring side of the same platform.

5. ManageEngine OpUtils

ManageEngine OpUtils is a network engineering toolset that includes IP address management and switch port mapping. It is useful for teams that want discovery, address tracking and port-to-device mapping without a full DDI deployment.

• Architecture: self-hosted Windows or Linux server with scan-based discovery.
• Fit: small and mid-sized networks that need IP tracking alongside everyday troubleshooting tools.
• Related: ManageEngine OpManager covers full monitoring from the same vendor.

6. Microsoft IPAM

Microsoft IPAM is a feature of Windows Server that discovers and manages IP ranges and monitors Microsoft DNS and DHCP servers. It carries no separate license beyond Windows Server and fits Microsoft-centric networks.

• Architecture: a Windows Server role that reads from Microsoft DHCP and DNS servers, with address data held in a built-in database.
• Fit: Active Directory-based organizations with Microsoft DNS and DHCP everywhere.
• Trade-off: limited coverage of non-Microsoft DNS and DHCP servers and little cloud awareness. See RFC 2131 for the DHCP behavior any of these tools must track.

7. NetBox

NetBox is an open source network source of truth that models IP addresses, prefixes, VLANs and devices with a REST API. It records intent rather than serving DNS or DHCP, which makes it popular with automation-minded teams.

• Architecture: Python application backed by PostgreSQL, extended through plugins, webhooks and a GraphQL and REST API.
• Fit: network automation, infrastructure-as-code and DevOps teams.
• Trade-off: you build discovery and DNS/DHCP synchronization yourself or add integrations.

8. phpIPAM

phpIPAM is a lightweight open source web IPAM that supports subnet management, VLANs and scan-based discovery. It is a low-cost way for small teams to move beyond spreadsheets.

• Architecture: PHP and MySQL/MariaDB web application with an API and optional scan agents.
• Fit: small organizations, labs and managed service providers on tight budgets.
• Trade-off: enterprise features such as granular workflow, HA and vendor support are limited.

Which IPAM tool should you choose?

Choose by who owns DNS and DHCP today. If you plan to consolidate core services, a DDI suite fits. If you only need visibility, a monitoring module, OpUtils, Microsoft IPAM or an open source tool is cheaper and faster to deploy.

• Consolidating DNS, DHCP and IPAM across sites and cloud: Infoblox, BlueCat or EfficientIP.
• Already on a monitoring suite: SolarWinds IPAM or ManageEngine OpUtils.
• Windows Server and Active Directory only: Microsoft IPAM.
• Automation and API-first: NetBox, with phpIPAM for simpler needs.

Whatever you pick, plan IPv6 from the start. The address space defined in RFC 8200 changes how subnetting and documentation work, and a tool that cannot track IPv6 will age quickly. Also test data quality: run discovery for two weeks and compare results with your known inventory before committing.

IPAM selection formula

Use a simple cost comparison to avoid choosing on features alone. Count the hours spent on address conflicts and manual reconciliation, and compare them with the annual cost of the tool plus its administration time.

Hours saved comes from fewer conflicts and faster provisioning, and avoided outage cost uses your own incident history. If the result is negative, a lighter tool is the better fit.

Frequently Asked Questions

How much does IPAM software cost?
Pricing varies widely. Open source tools such as NetBox and phpIPAM have no license fee but need hosting and admin time. Infoblox, BlueCat and SolarWinds are typically sold by quote or by tiered licenses, so request current pricing from each vendor and include appliances and support in the total.

Can I migrate from spreadsheets to IPAM without downtime?
Yes. Import existing subnets and addresses by CSV, run discovery in read-only mode for a few weeks, and reconcile differences before enabling DHCP or DNS integration. Keep the spreadsheet as a fallback until discovery matches your known inventory.

Is Microsoft IPAM enough for a Windows-only network?
Often yes. Microsoft IPAM manages Microsoft DNS and DHCP servers and ships with Windows Server. It becomes limiting once you add non-Microsoft DNS/DHCP, large multi-site automation or strong cloud inventory needs, at which point a dedicated IPAM or DDI product is a better fit.
