Overview

Subnetly brings IP address management, DNS, DHCP, discovery, and network visibility together in a hybrid DDI platform. It is best suited to SMB network teams and MSPs managing multiple customer environments. Its breadth is a strength, but the free tier is narrow and scaling beyond small deployments means a substantial monthly commitment.

Key features

IPAM and network visibility

The dashboard connects address utilization with ownership and flags conflicts and orphaned addresses. That gives administrators practical ways to spot allocation problems rather than relying on an inventory alone; QBR data export also helps teams prepare network status for quarterly reviews. AI insights are aimed at surfacing capacity risks and configuration gaps, though they are an added guidance layer rather than a substitute for operational oversight.

DNS, DHCP, and discovery

Local agents support authoritative DNS zones and DHCP scopes, with the SaaS console coordinating records and configurations. Agents scan active segments using ARP, SNMP, and ICMP and populate a hardware asset registry. Combining these jobs is useful for teams that want one operational view of DDI and discovered assets; organizations needing only basic IP tracking may not need that breadth.

Hybrid deployment and integrations

Deployment options include Docker, Kubernetes/Helm, Windows Server, and Linux daemons. Agents make outbound connections over HTTPS or TLS, avoiding the need for open inbound ports or VPN tunnels. REST APIs and monitoring webhooks support automation, but access varies by paid tier, so teams should match their integration needs to the plan before choosing a low-cost option.

MSP controls include customer and site separation, technician roles, and customer-ready audit records. Those controls make the product more relevant to service providers than a single-environment IPAM tool, while the privacy policy describes safeguards such as encryption in transit, access controls, tenant isolation, audit logging, monitoring, and secure secret handling. It also cautions that no transmission or storage method is completely secure.

Pricing

Subnetly is freemium, with monthly-billed plans from 49.00 USD per month. The Free plan costs 0.00 USD per month and allows 256 IPAM addresses, 10 subnets, two DHCP pools, one private and one public DNS zone, 100 DNS records, one site, one agent, and one user. It also caps AI Advisor messages at 10 per month and AI documentation generation at one per month, with seven-day history retention. That is a useful evaluation tier, but the single-user and single-site limits make it a poor fit for a working team.

Starter costs 49.00 USD per month and raises capacity to 2,500 addresses, 100 subnets, 25 DHCP pools, five private and three public DNS zones, 1,000 DNS records, three sites, three agents, and three users. It includes 100 AI Advisor messages monthly, 10 documentation generations, 30-day history, and email support. This is the practical entry point for a small deployment, but the three-user and three-site caps leave little room for expansion.

Pro costs 149.00 USD per month, with 10,000 addresses, 500 subnets, 100 DHCP pools, 25 private and 10 public DNS zones, 10,000 DNS records, and limits of 10 sites, agents, and users. Its AI quotas rise to 500 messages and 50 documentation generations monthly, and history retention reaches 180 days. It suits a growing team that needs more capacity and a longer audit window than Starter provides.

For service providers, MSP Starter costs 199.00 USD per month and covers five customer tenants, 10,000 addresses, 15 sites and agents, three technician users, and five client users. MSP Growth costs 499.00 USD per month for 25 tenants, 50,000 addresses, 75 sites and agents, 10 technician users, and 25 client users. MSP Scale costs 999.00 USD per month and supports 75 tenants, 200,000 addresses, 250 sites and agents, 25 technician users, and 100 client users. These tiers scale customer and technician capacity alongside infrastructure limits, making them more relevant to MSPs than buying a general business tier.

Business costs 399.00 USD per month and provides 50,000 addresses, 2,500 subnets, 500 DHCP pools, 50 sites, agents, and users, plus 2,500 AI Advisor messages and 250 documentation generations monthly. It includes one-year history retention, a 21-day trial, and priority support. Starter and Pro include 14-day trials; signup requires no credit card. Enterprise and MSP Enterprise have custom pricing and contract billing, with custom limits and retention, premium support, and private deployment options; Enterprise also offers migration assistance, while MSP Enterprise adds 75+ tenants, custom MSP resource limits, SCIM options, and dedicated onboarding. Their configuration is for organizations beyond the fixed tiers, not buyers seeking a predictable posted monthly price.

Platforms

Subnetly supports API, iOS, Linux, web, and Windows. Its hybrid deployment options are Docker, Kubernetes/Helm, Windows Server, and Linux daemon, so teams can place agents in their environments while coordinating from the SaaS console.

Who it's for

Subnetly is a strong fit for SMB administrators who manage IP allocation, DNS, DHCP, and asset discovery together, and for MSPs that need separated customer environments and technician controls. It is less compelling for a small team that needs only an IP inventory, or for buyers who cannot justify recurring costs beyond the tightly limited free tier.

Pros and cons

Pros: IPAM, DNS, DHCP, discovery, and visibility share a platform, reducing the need to manage these functions separately.
Pros: Outbound-only agent communications avoid open inbound ports and VPN tunnels.
Pros: MSP plans scale tenant, site, agent, technician, and client-user allowances for multi-customer work.
Cons: The free plan's one user, one site, and 256-address cap restrict it to evaluation or very small environments.
Cons: Starter is capped at three users, sites, and agents, so teams may need to move to a higher-priced tier as they expand.
Cons: API and webhook access varies by paid tier, making plan selection important for automation-dependent deployments.

Alternatives

Tidal LightMesh is worth considering when a smaller free IPAM footprint is sufficient: its free plan allows one user, fewer than 1,000 IPs, unlimited subnets, basic IPAM, and DHCP discovery; its Pro plan is 35.00 USD per month. GestióIP is a free-software alternative for teams that want a standard IPAM package, with a separately priced configuration-management module. .NET offers an open-source option with a free tier for up to 1,000 nodes. Cygna DDI is another DDI option, with perpetual-license or subscription terms. IPplan suits teams seeking a free, self-hosted web application. Obelinf is an alternative to consider for rack and device tracking, with a free Personal plan for one user, one organization, one site, four racks, and 30 devices. NIPAP is a free, MIT-licensed option for teams that prefer open-source IP address management. teemIP offers a free Community edition with open-source code and community resources.

Verdict

Choose Subnetly if your team needs a shared system for IPAM, DNS, DHCP, discovery, and visibility, particularly when local agents and MSP customer separation matter. Its main advantage is that joined-up scope; its main drawback is that the free tier is too constrained for most teams, while scaling brings meaningful monthly costs. Teams seeking only basic address tracking or a free self-hosted tool should look elsewhere.
