Overview

GestióIP is web-based software for managing IPv4 and IPv6 addresses, networks, and subnets. It is best suited to network teams that want discovery and DNS/DHCP workflows alongside IPAM, especially if they can self-host or prefer a managed cloud instance. Its free GPLv3 core is capable; device configuration management and API access are commercial extras.

Key features

Network discovery pulls data from Layer III routing tables and identifies hosts through ping, DNS, SNMP, and DHCP lease processing. That gives teams several paths to build and maintain an address inventory, though the range of discovery inputs is most useful when those services are already part of the environment.

GestióIP supports secure dynamic DNS updates with TSIG or GSS-TSIG across Microsoft DNS, BIND, and other DNS products. It can synchronize leases from ISC DHCPD, ISC KEA, Microsoft DHCP server, or generic lease files. These integrations connect IPAM records with address assignment and DNS operations rather than leaving them as separate bookkeeping tasks.

For planning and troubleshooting, the software includes ping and DNS A/PTR checks, free-range display, subnet split and join operations, a subnet calculator, and a hierarchical IPv6 addressing-plan builder. Excel import and CSV export support data migration, while BIND and tinydns forward and reverse zone-file generation can feed DNS workflows.

The paid API supports CRUD operations and advanced actions such as locating or reserving the first free network or IP address. The optional Configuration Management Module backs up and restores device configurations, runs commands across multiple devices, retains configuration history, and supports diffs and searches. Those are meaningful additions for teams that want configuration workflows tied to IPAM, but they are not part of the free core.

The web interface needs no additional client software. Deployment options include installation packages and Docker Compose instructions for self-hosting. GestióIP Cloud offers a pre-installed SaaS instance intended to be ready in one day; it uses VPN-secured browser access, dedicated virtual servers, automatic database backups, and selectable DigitalOcean regions.

Pricing

GestióIP IPAM costs 0.00 USD per free and includes the standard package under GPLv3. That is the right fit for teams able to manage deployment themselves and whose needs center on IPAM, discovery, subnet planning, and DNS/DHCP integration. Commercial support is available by email or telephone with guaranteed response times; cloud subscriptions include email support.

The Configuration Management Module is sold as a one-year license, priced by device cap: 400.00 USD per year for up to 50 devices, 700.00 USD per year for up to 100, 1500.00 USD per year for up to 500, 2800.00 USD per year for up to 1000, and 5000.00 USD per year for up to 2500. Choose a tier based on the number of devices whose configurations need management; the caps make the smaller licenses unsuitable once a fleet exceeds their limit. The API is also commercial, but no separate API price is given. GestióIP Cloud is a paid subscription option, with custom pricing.

Platforms

GestióIP supports API, Linux, self-hosted, web, and Windows environments. Its hybrid deployment model gives teams a choice between running the software themselves and using the cloud service; the web interface avoids a separate client installation.

Who it's for

GestióIP is a strong choice for network administrators who need IPv4 and IPv6 inventory, automated discovery, subnet planning, and coordination with DNS and DHCP. It also suits teams that value open-source software and can operate a self-hosted deployment. Organizations that want managed hosting can choose GestióIP Cloud, while teams needing API automation or device configuration history should budget for commercial features. It is less compelling for a small environment that needs only a tightly capped hosted IPAM service.

Pros and cons

Pros: The free GPLv3 core combines discovery, IPv4/IPv6 planning, DNS integration, and DHCP lease synchronization, giving self-hosting teams substantial IPAM capability without a license fee.
Pros: Excel import, CSV export, and BIND/tinydns zone-file generation help connect existing records and DNS operations to the address database.
Pros: Cloud deployment includes VPN-secured access, dedicated virtual servers, and automatic database backups, reducing the operational work of running an instance.
Cons: API access and configuration management are commercial features, so automation or device-configuration workflows add cost beyond the free core.
Cons: The configuration module's device caps require selecting a license tier that matches fleet size, and the largest supplied tier covers up to 2500 devices.
Cons: The free software option is distinct from the pre-installed cloud service; teams seeking managed hosting need a subscription rather than the free self-hosted package.

Alternatives

For a different mix of IPAM and network tools, compare IP Address Management Software and Network Documentation Software.

Subnetly is worth considering when a hosted free tier with explicit resource limits suits the job: its free plan covers 256 IPAM addresses, 10 subnets, 2 DHCP pools, and one private and public DNS zone each.
.NET is an open-source option for Windows, macOS, Linux, iOS, and Android, with a free tier for up to 1,000 nodes.
Tidal LightMesh has a free tier for one user and fewer than 1,000 IPs, with unlimited subnets, basic IPAM, and DHCP discovery; consider it if those limits fit better than GestióIP's self-hosted approach.
IPplan is a free, GPL self-hosted web application for readers who want a simpler open-source alternative.
NIPAP is a free, MIT-licensed self-hosted option with API support.
Obelinf offers a free Personal plan for one user, one organization, one site, four racks, and 30 devices, which may suit readers focused on a small infrastructure inventory.
phpIPAM is free open-source IP address management software with a self-hosted installation.
SpatiumDDI is a free option for readers comparing another open-source infrastructure product.

Verdict

Choose GestióIP if your team wants a free, self-hosted IPAM foundation with real discovery, subnet-planning, and DNS/DHCP integration, or needs a managed cloud instance with defined security and backup features. Its main trade-off is that API automation and device configuration management sit outside the free core; teams that need those capabilities should account for the annual device-tier costs before choosing it.
