Overview

Subnetly is a hybrid DDI platform that combines IP address management with DNS, DHCP, network discovery and visibility. It is best suited to SMB network teams and MSPs managing multiple customer environments. Its broad scope is a strength, but the free tier is tightly capped and larger operations will need a paid or custom plan.

Key features

IP address management and visibility

The dashboard tracks IP use and ownership, flags conflicts and orphan addresses, and supports QBR data exports. That makes it useful not just for keeping an address inventory, but also for spotting allocation issues and preparing network reviews. AI insights target capacity risks and configuration gaps; teams that prefer to make those judgments themselves may place less value on that layer.

DNS, DHCP and discovery

Local agents handle authoritative DNS zones and DHCP scopes, while the SaaS console coordinates records and configurations. Agents scan active segments with ARP, SNMP and ICMP to build a hardware asset registry. Keeping these functions together should suit teams seeking a shared view across DDI and discovered assets; organizations that need only basic IPAM may find the platform broader than necessary.

Deployment and integrations

Deployment options include Docker, Kubernetes/Helm, Windows Server and Linux daemons. Agents communicate outbound over HTTPS or TLS, without open inbound ports or VPN tunnels, which can be a practical fit for networks where inbound access is undesirable. REST APIs and monitoring webhooks support automation with scripts and third-party tools, though access varies by paid tier.

For MSPs, customer and site separation, technician roles and customer-ready audit records address the need to keep client environments and operational records distinct. Subnetly's privacy policy describes safeguards that may include 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 has a free plan and monthly paid plans. Starter and Pro include 14-day trials, while Business has a 21-day trial; signup requires no credit card.

Free — 0.00 USD per month, billed monthly: 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 includes 10 AI Advisor messages and one AI documentation generation per month, with seven-day history retention. This is suitable for a small evaluation or very limited deployment, but the single-user, single-site caps leave little room for a growing team.
Starter — 49.00 USD per month, billed monthly: 2,500 IPAM addresses, 100 subnets, 25 DHCP pools, five private and three public DNS zones, 1,000 DNS records, three sites, agents and users, 100 AI Advisor messages and 10 documentation generations monthly, and 30-day history retention. Email support is included. This is the entry paid tier for a small team that needs more than the free caps allow.
Pro — 149.00 USD per month, billed monthly: 10,000 IPAM addresses, 500 subnets, 100 DHCP pools, 25 private and 10 public DNS zones, 10,000 DNS records, 10 sites, agents and users, 500 AI Advisor messages and 50 documentation generations monthly, with 180-day history retention. It suits teams needing more scale and longer history than Starter provides.
MSP Starter — 199.00 USD per month, billed monthly: Five customer tenants, 10,000 IPAM addresses, 500 subnets, 100 DHCP pools, 25 private and 10 public DNS zones, 10,000 DNS records, 15 sites and agents, three MSP technician users and five client users. It includes 500 AI Advisor messages and 50 documentation generations monthly. The tenant and role structure makes this more appropriate than Pro for a small provider managing several clients.
Business — 399.00 USD per month, billed monthly: 50,000 IPAM addresses, 2,500 subnets, 500 DHCP pools, 100 private and 50 public DNS zones, 50,000 DNS records, 50 sites and agents, 25 users, 2,500 AI Advisor messages and 250 documentation generations monthly, with one-year history retention. Priority support and a 21-day trial are included. It fits larger in-house operations that need expanded capacity and longer audit history.
MSP Growth — 499.00 USD per month, billed monthly: 25 customer tenants, 50,000 IPAM addresses, 2,500 subnets, 500 DHCP pools, 100 private and 50 public DNS zones, 50,000 DNS records, 75 sites and agents, 10 MSP technician users and 25 client users. It includes 2,500 AI Advisor messages and 250 documentation generations monthly. This is the step up for MSPs whose tenant or technician needs exceed MSP Starter.
MSP Scale — 999.00 USD per month, billed monthly: 75 customer tenants, 200,000 IPAM addresses, 10,000 subnets, 2,000 DHCP pools, 500 private and 150 public DNS zones, 200,000 DNS records, 250 sites and agents, 25 MSP technician users and 100 client users. It is aimed at providers needing substantially more customer and infrastructure capacity than MSP Growth, with premium support.
Enterprise and MSP Enterprise — custom pricing: Enterprise offers custom limits, SSO/SAML options, custom retention, migration assistance, premium support and private deployment options. MSP Enterprise adds support for 75+ customer tenants, custom IPAM, DNS, DHCP, site and agent limits, SCIM options and dedicated onboarding. These plans are for organizations whose scale or deployment needs exceed the fixed tiers.

Platforms

Subnetly supports API, iOS, Linux, web and Windows. Its hybrid deployment options span containerized deployments, Kubernetes/Helm, Windows Server and Linux daemons, so teams can place agents in their network environment while coordinating through the SaaS console.

Who it's for

Subnetly is aimed at SMBs and MSPs, particularly administrators responsible for address allocation, DNS and DHCP configuration, and network asset oversight. Its multi-tenant MSP plans are the clearest fit for service providers; a smaller in-house team can start with Free or Starter. It is less compelling for buyers who need only a basic address inventory or want extensive capacity without moving beyond a small plan.

Pros and cons

Pros: IPAM, DNS, DHCP and active-segment discovery are brought into one platform, which can reduce the need to reconcile separate network inventories.
Pros: Outbound-only agent communication avoids open inbound ports and VPN tunnels, a useful deployment characteristic for managed networks.
Pros: MSP tiers define customer tenants, technician seats and client users, making their capacity easier to assess against a provider's client base.
Cons: The free plan's one user, one site and one agent cap it at small-scale use, even though it includes several core functions.
Cons: Several paid plans impose distinct quotas on addresses, sites, agents, users and AI usage, so buyers must match multiple limits rather than price alone.
Cons: Enterprise and MSP Enterprise require custom pricing, which makes those tiers harder to compare directly with the fixed monthly plans.

Alternatives

Tidal LightMesh is worth considering for a lower-cost starting point: its free plan allows one user and fewer than 1,000 IPs with unlimited subnets and DHCP discovery, while Pro is 35.00 USD per month.
GestióIP may suit buyers seeking free IPAM software or a configuration-management module priced per year.
teemIP is an option for teams that want a free community offering with open-source code.
Danbyte is worth comparing for buyers seeking free, self-hosted software with all features included and no seat license.
Obelinf may suit buyers looking for a freemium option on API and web platforms.
phpIPAM is a free, self-hosted IP address management option for teams that do not need Subnetly's combined DDI scope.
SpatiumDDI is another free option for buyers comparing DDI software.
Infoblox Cloud Network Automation uses token-based licensing; consider it if that licensing model fits your purchasing approach.

Verdict

Subnetly is a strong fit for SMB network administrators and MSPs who want IPAM, DNS, DHCP and discovery under one roof, with outbound-only agents and dedicated multi-tenant tiers as notable advantages. Choose it when that joined-up scope and its capacity tiers match your environment; look elsewhere if a basic IPAM tool or a more open-ended free deployment is enough.
