DDI and network visibility
without enterprise complexity
Subnetly replaces scattered spreadsheets and bloated tools with a central control plane. Deploy lightweight agents for local DNS, DHCP, discovery, IPAM, and live documentation.
Centralized IP Address Management
Stop tracking subnets in spreadsheets. Subnetly automatically updates IP utilization, flags conflicts, and tracks ownership across all local sites.
Designed For Network Practitioners
Built for lean teams that have outgrown Excel
For SMB IT Teams
Unify internal subnets, scopes, and domains in a self-updating interface. Stop guessing which IPs are available.
For MSP Providers
Standardize client network documentation, discover unknown switch ports, and automate auditing reports under one panel.
For Infrastructure Admins
Implement robust local DNS & DHCP resolving with the simplicity of central SaaS backups and RBAC permissions.
The Spreadsheet Problem
Spreadsheets fall behind tickets
A technician changes a lease pool or adds a temporary record, but skips updating the central inventory. Soon, you have IP conflicts and ghost assets. Subnetly automates this process continuously.
Comparing Workflows
Manual Tracking Gaps
Documentation outdates as soon as a technician changes a lease or deploys a firewall.

Simple Deployment
Up and running in 60 seconds
Subnetly keeps critical network services local. Install our agent near your nodes via Docker, Helm, or system binaries. It automatically registers with the SaaS portal and begins asset discovery.
Deploy the Local Agent
Spin up a lightweight agent on site using a simple container or system script.
Automatic Subnet Scan
Agent maps ARP caches, DHCP pools, and local resolver caches without complex setups.
Manage Centralized DDI
Configure records, track subnets, and export clean auditor reports from your dashboard.
Deploy Agent Container
Run the lightweight agent container locally on any host with Docker installed. Communicates outbound to the SaaS control plane securely.
# 1. Pull the official Subnetly agent image
docker pull subnetly/agent:latest
# 2. Run the agent container with registration key
docker run -d \
--name subnetly-agent \
--restart unless-stopped \
-e AGENT_KEY="sub_agent_38ea127bcf" \
-e SUBNET_SCAN="10.10.10.0/24" \
subnetly/agent:latestCore Capabilities
Everything you need in one operating model
IP Address Management (IPAM)
Track IP blocks, subnets, utilization, and stale entries from a single web dashboard. Eliminate overlap conflicts automatically.
Local DNS Servers
Configure local authoritative DNS zones locally via agents. Central SaaS console coordinates records while resolving stays sub-millisecond.
Centralized DHCP Scopes
Standardize lease pools and reservations across environments. Control local scopes without logging into disconnected server consoles.
Automated Scan Discovery
Local agents scan active segments using ARP, SNMP, and ICMP to populate a real-time hardware asset registry.
Proactive AI Insights
Subnetly highlights capacity risks, orphaned addresses, IP conflicts, and configuration gaps before they impact client operations.
Lightweight Local Agents
Agents maintain core network services locally. SaaS portal aggregates control, security updates, and client reports.
Agent Footprint
Fits your existing architecture
Whether you run virtualized clusters, dedicated physical appliances, cloud subnets, or Windows Server Active Directory hosts, our agents deploy natively.
Docker Containers
Run agents inside minimal containers. Zero external dependencies.
Kubernetes/Helm
Deploy daemonsets natively to monitor container network service interfaces.
Windows Server
Native service binaries integrate with Windows DHCP scopes and AD DNS.
Linux Daemons
Lightweight background daemons optimized for Ubuntu, Debian, and CentOS.
