Best IP Address Management (IPAM) Software

GestioIP is an open source IPAM whose strength is automated discovery, which addresses the fundamental weakness of any address record: it is only as accurate as the last time somebody updated it by hand.

Discovery works through several mechanisms rather than one. Hosts are found via ping, DNS and SNMP, layer three device routing tables are read, VLANs are discovered via SNMP, and DHCP lease information is processed directly. Combining these matters because each misses something on its own: ping misses hosts that do not respond, DNS misses anything unregistered, and SNMP only sees managed equipment.

DHCP synchronisation is supported against ISC DHCPD, ISC KEA, Microsoft DHCP server and a generic leases file format. Reading leases is the most direct route to knowing which addresses are genuinely in use, since the DHCP server is the authority that issued them.

The system also integrates with Microsoft DNS, BIND and other DNS products, and includes VLAN management, management of leased and dial up lines, and autonomous system management. Automated backups of the GestioIP database are provided and a high availability configuration is available.

There is no licence cost, which places GestioIP alongside phpIPAM as a credible option for networks that need real address management without an enterprise procurement. The discovery depth is the main reason to prefer it, since it reduces how much of the record depends on somebody remembering to update it.

SolarWinds IP Address Manager provides IPAM within the wider SolarWinds portfolio, which is built as a set of modules sharing a common platform rather than as one monolithic product.

That modularity is the practical argument for it. A network team already running SolarWinds Network Performance Monitor, NetFlow Traffic Analyzer or Network Configuration Manager adds address management to a console its staff already know, with one set of credentials and one place to look, rather than introducing a separate tool with its own conventions.

The surrounding portfolio is extensive, spanning observability both self hosted and as a service, server and application monitoring, security event management, virtualisation management, access rights management, database performance analysis and incident response. For an organisation consolidating vendors that breadth is the attraction.

Pricing is published across the portfolio starting at 8 dollars per node per month for monitoring and observability, with volume discounts available on request. Other portfolio areas are priced on their own units, including database monitoring from 142 dollars per database per month and IT service management from 39 dollars per technician, so the address management component should be quoted specifically.

phpIPAM is a free open source IP address management application, and it occupies the practical middle ground between managing addresses in a spreadsheet and buying an enterprise DDI platform.

That gap is real and widely occupied. A great many networks are documented in a shared spreadsheet that is perpetually out of date, because the alternative has historically been an expensive commercial product requiring its own project to deploy. A free tool covering the core function well is often the correct answer.

The functional set covers the essentials properly: VLAN management, VRF management, an IPv4 and IPv6 calculator, IP database search, email notifications and custom field support. IPv6 support matters more than it once did, and the calculator addresses the fact that IPv6 subnetting is genuinely hard to do reliably in one's head.

Custom fields are what let an installation match how a particular organisation actually thinks about its addresses, rather than forcing its records into someone else's schema. The project maintains changelogs, translations and current installation guides, including a complete walkthrough for deploying the latest stable version on Ubuntu Server with nginx. There is no licence cost.

NetBox is the source of truth model for network and data centre infrastructure, and it occupies a different position from conventional IPAM tools. Rather than discovering what exists, it holds the authoritative record of what is intended to exist.

That distinction drives everything else. A discovery tool tells you the network's current state, including its mistakes; an intent model tells you what the state should be, which is what allows misconfiguration to be identified as a difference rather than accepted as fact. NetBox Labs describes an Infrastructure Graph as an API first, agent native model of every network and infrastructure object.

Operational Intelligence closes the loop by comparing live infrastructure state against that intent in real time, which is the mechanism that turns documentation from something written once and left to rot into something continuously checked.

NetBox AI adds natural language querying, smart automation and AI assisted orchestration, with the agent native framing reflecting that a structured infrastructure model is exactly what an AI agent needs in order to act safely. The platform is engineered for hyperscalers with multi region support, enterprise service level agreements and data centre scale. Pricing is not published.

Micetro is a DDI orchestration platform, DDI being the industry term for the combination of DNS, DHCP and IP address management. It now sits within BlueCat Networks following the acquisition of Men&Mice, and continues under the Micetro name.

Orchestration rather than replacement is the product's defining choice. Most organisations already run DNS and DHCP on Microsoft servers, BIND, cloud provider services or some combination accumulated over years. Micetro manages that existing estate through a single web interface rather than requiring it to be migrated onto new infrastructure, which is a materially smaller undertaking.

Coverage spans on premises, cloud and branch networks together. That breadth matters because hybrid deployments are where address management actually breaks down: a subnet allocated in a cloud account by one team can collide with an on premises range nobody thought to check.

Micetro sits alongside BlueCat's wider portfolio, including Integrity as a full stack API first DDI platform and Horizon as a SaaS first intelligent NetOps platform unifying DNS, DHCP, IPAM, security and observability, with extensions for network automation and integration. Pricing is not published.

ManageEngine OpUtils combines IP address management with switch port management, and pairing those two is the product's central idea rather than a bundling convenience.

The reason is a question network engineers face constantly: an address is in use, but by what, and plugged in where. Address management alone answers the first half and leaves the engineer walking to the comms room for the second. Mapping addresses to the physical switch ports they connect through closes that gap and turns tracing a device into a query.

DNS management centralises zone and record administration across Microsoft DNS servers, maintaining accurate name resolution, eliminating stale records and proactively detecting lookup failures, with secure communication enabled through WinRM. Stale DNS records are a persistent source of confusing faults, because a name that resolves to an address nothing answers on produces a failure that looks like a network problem rather than a data problem.

Subnet utilisation is presented visually so an approaching exhaustion is visible before it causes allocation failures, and the product discovers across equipment from multiple vendors including Microsoft, Infoblox and Cisco environments. Pricing is not published on the captured page.

Infoblox is among the largest vendors in enterprise DDI, and its current portfolio makes clear that DNS security rather than address administration is where the company now concentrates.

That connection is real rather than marketing. DNS sees every connection an organisation's devices attempt, which makes it simultaneously critical infrastructure and the best available vantage point for detecting compromise. A vendor already operating an organisation's DNS is well placed to inspect it, which is why DDI and DNS security converged.

The security line includes Infoblox Threat Defense for hybrid DNS layer protection deployed anywhere, DNS Infrastructure Protection to block attacks against the DNS servers themselves, and exposure management for detecting risk. Protecting the infrastructure is a distinct problem from using it defensively, since DNS going down takes everything else with it.

Infoblox IQ applies agentic AI workflows grounded in DNS threat intelligence to accelerate analysis in a security operations centre and scale investigation and response. A security ecosystem provides integrations to automate response across other tools. Pricing is not published, which is standard for infrastructure sold to large enterprises.

EfficientIP SOLIDserver provides DDI alongside network automation and DNS security, and the depth of its DNS protection range is what distinguishes it from general address management tools.

The security products address distinct attack shapes rather than presenting one undifferentiated defence. DNS Guardian provides adaptive security for service continuity and data protection, DNS Firewall blocks DNS based malware activity, and DNS Blast provides carrier grade protection against DNS denial of service attacks.

Separating those is technically correct. Protecting users from resolving malicious domains and keeping a resolver standing under a volumetric flood are different engineering problems, and a product treating them as one usually does one of them badly. DNS Client Query Filtering adds application access control to limit how far an attack can spread.

Edge DNS GSLB extends into application delivery, optimising performance from the edge through global server load balancing, which uses DNS to direct users to the best available location. The company also publishes DNS threat intelligence for proactive security and organises its material by IT initiative, including zero trust and visibility. Pricing is not published.
