Subnetly

Overview

Subnetly is a hybrid DDI platform for teams that need to manage IP addresses, DNS, DHCP and network discovery together. It is best suited to SMB network administrators and MSPs managing multiple customer environments. Its breadth is compelling, but the free plan is tightly capped and meaningful capacity requires a paid tier.

Key features

IP address management

The dashboard tracks address use and ownership, flags conflicts and orphaned IPs, and supports QBR data exports. That makes it more useful than a bare address inventory for teams that need to spot allocation issues and report network status. AI insights target capacity risks and configuration gaps, though the value of those insights depends on whether a team wants another layer of automated guidance.

DNS, DHCP and discovery

Local agents support authoritative DNS zones and DHCP scopes, while the SaaS console coordinates records and configurations. Agents discover assets on active segments through ARP, SNMP and ICMP scans, building a hardware registry alongside the address-management view. This joined-up scope suits teams looking to consolidate routine DDI work; it may be more platform than needed for organizations seeking only a lightweight IPAM tool.

Hybrid deployment and integration

Deployment options include Docker, Kubernetes/Helm, Windows Server and Linux daemons. Agents communicate outbound over HTTPS or TLS without requiring open inbound ports or VPN tunnels, a practical fit for environments where inbound access is undesirable. REST APIs and monitoring webhooks support automation, but API and integration access varies by paid tier.

MSP administration and security

Customer and site separation, technician roles and customer-ready audit records are aimed squarely at service providers handling several environments. The privacy policy describes safeguards such as encryption in transit, access controls, tenant isolation, audit logging, monitoring and secret handling, while acknowledging that no transmission or storage method can be guaranteed completely secure.

Pricing

Subnetly has a free tier and monthly paid plans; paid pricing starts at $49 a month. Free, Starter, Pro and Business trials run 14, 14, 14 and 21 days respectively, with no credit card required for trial signup.

The lower tiers trade capacity, seats and retention for lower monthly cost; MSP plans add explicit tenant and technician limits rather than simply scaling general team seats. All listed monthly plans are billed monthly, so there is no annual-price assumption in the displayed terms.

Platforms

Subnetly is available through web, iOS, Linux, Windows and API access. Its hybrid deployment also supports Docker, Kubernetes/Helm, Windows Server and Linux daemon agents, giving infrastructure teams options to fit existing environments.

Who it's for

Subnetly suits SMBs that want IPAM, authoritative DNS, DHCP and discovery in one administrative system, especially when address ownership and audit history matter. MSPs get controls designed for separating customers and sites, though the technician-seat ceilings on entry MSP plans should be checked against team size. Teams that need only a small self-hosted IP inventory may not need a SaaS platform with tiered integrations and AI quotas.

Pros and cons

Pros

• Combines address tracking, DNS, DHCP and segment discovery, reducing the need to treat those tasks as unrelated inventories.
• Outbound-only agent communication avoids opening inbound ports or relying on VPN tunnels for agent connectivity.
• MSP customer and site separation, role controls and customer-ready audit records address service-provider workflows directly.
• Trial periods range from 14 to 21 days and do not require a credit card at signup.

Cons

• The free tier's 256-address and single-site ceiling is restrictive for anything beyond a small evaluation.
• History ranges from 7 days on Free to 30 days on Starter, so longer audit horizons require an upgrade.
• REST API and integration access varies by paid tier, which can complicate planning for automation-dependent teams.
• Entry MSP Starter limits providers to 3 technician users, even though it supports 5 customer tenants.

Alternatives

For a category-wide shortlist, compare IP Address Management Software and DHCP Management Software.

• Tidal LightMesh is worth considering for a free IPAM option with unlimited subnets and DHCP discovery, or a $35 a month Pro plan.
• GestióIP fits readers looking for free IPAM software, with a separately priced configuration-management module at $400 a year for up to 50 devices.
• Netipam is another free Linux, self-hosted and web option.
• teemIP offers a free, open-source Community plan for teams preferring that model.
• phpIPAM is a free, self-hosted IP address management option.
• SpatiumDDI is a free option for teams seeking a Linux, self-hosted and web deployment.
• Danbyte is a free and open-source self-hosted option with all features included and no seat license.
• Obelinf is an alternative with a free Personal tier and a paid Teams plan.

Verdict

Choose Subnetly if you want one hybrid system for IPAM, DNS, DHCP and discovery, or need customer-separated controls for MSP work. Its strongest case is the breadth of DDI coverage paired with deployment flexibility; its main drawback is that capacity, history and integration access are tier-bound, and even the free plan is best treated as an evaluation rather than a durable team setup.
