ManageEngine OpUtils

ManageEngine OpUtils is a network management toolset for monitoring, diagnosing, and troubleshooting IP resources and network devices. It manages IP address space, maps devices to switch ports, and combines DNS, DHCP, and IP address management, including Microsoft DNS and DHCP management. More than 30 network utilities cover diagnostics, SNMP, Cisco, address monitoring, and connectivity. OpUtils can detect rogue devices, alert on IP conflicts and ARP spoofing, and apply DHCP MAC-based filtering. It supports role-based access control and two-factor authentication. Integrations include Microsoft DHCP and DNS, Cisco Meraki controllers, and ManageEngine products such as OpManager and NetFlow Analyzer. APIs can connect it with third-party IT management and service desk software. The downloadable product is offered for 64-bit Windows and Linux, with browser access and iOS and Android apps for monitoring network addresses and ports. The free edition covers one Class C subnet and one switch. Paid plans start at $138, and a 30-day trial is listed. OpUtils can monitor Microsoft DHCP scopes and leased addresses, but its IPAM cannot assign IP addresses to devices.

OpUtils combines IP address, switch-port, DNS, and DHCP management with network utilities and security controls. Note the free edition’s scope and the stated limit on assigning IP addresses.

OpUtils suits teams monitoring IP resources, network devices, DNS, DHCP, and switch ports. The free edition is described as intended for small companies, while paid plans include broader capabilities.

Overview

ManageEngine OpUtils is a network management toolset for tracking IP resources and network devices. It is best suited to administrators who need IP address and switch-port visibility alongside diagnostics and security controls. Its broad toolkit is useful, though the free edition is small and IPAM cannot assign addresses to devices.

Key features

OpUtils brings IP address management and switch-port mapping together, so administrators can track address space and see which devices connect through switch ports. Its DDI tools combine DNS, DHCP, and IP management, including Microsoft DNS and DHCP. The gap is address provisioning: OpUtils can monitor Microsoft DHCP scopes and leased addresses, but its IPAM cannot assign addresses to devices. Teams that expect IPAM to handle allocation as well as monitoring should look elsewhere.

More than 30 network utilities cover diagnostics, SNMP, Cisco, address monitoring, and connectivity. Rogue-device detection, alerts for IP conflicts and ARP spoofing, and DHCP MAC-based filtering give network administrators practical tools for spotting or restricting unwanted activity. Role-based access control and two-factor authentication add access protections.

Integrations with Microsoft DHCP and DNS, Cisco Meraki controllers, and ManageEngine products such as OpManager and NetFlow Analyzer suit organizations already using those systems. APIs provide a way to connect OpUtils with third-party IT management and service desk software. Phone support runs 24 hours a day, Monday through Friday, a useful option for teams needing weekday coverage.

Pricing

OpUtils uses a freemium model, with a free plan and paid plans starting priced on request. A 30-day trial is available. The free edition is aimed at small companies, but its limit of one Class C subnet and one switch makes it suitable only for a small environment; it includes basic IP and network scanning.

Professional is priced on request and covers 250 IPs, switch ports, IP address management, switch-port mapping, rogue-device detection, and more than 30 network tools. It fits teams that need those capabilities without the full DDI management included in the next tier. Management is priced on request and also covers 250 IPs, switch ports, switch-port mapping, rogue-device detection, and the network tools, while adding full DDI management. That tier is the better fit when DNS and DHCP management belong in the same product. The listed plans give a 250-IP allowance for each paid tier, so teams with larger address inventories should account for that limit when choosing.

Platforms

The downloadable product runs on 64-bit Windows and Linux, with access through a web browser. Mobile apps for iOS and Android let administrators monitor network addresses and ports. The platform range makes it workable for teams with mixed desktop and mobile access needs.

Who it's for

OpUtils is a strong fit for network administrators who want IPAM, switch-port mapping, diagnostics, and device safeguards in one toolkit, especially where Microsoft DNS or DHCP, Cisco Meraki, or ManageEngine products are already in use. Small companies can use the free edition to cover a single subnet and switch. Teams that need broader coverage, full DDI management, or third-party integrations can consider a paid plan or its APIs. It is a poor fit for organizations that require IPAM to assign addresses to devices.

Pros and cons

• Pros: IPAM and switch-port mapping are combined, helping teams relate address records to connected devices.
• Pros: More than 30 network utilities, plus rogue-device detection and IP-conflict and ARP-spoofing alerts, cover monitoring and troubleshooting needs.
• Pros: Microsoft, Cisco Meraki, and ManageEngine integrations, along with APIs, provide routes into established network and service desk workflows.
• Cons: The free edition covers only one Class C subnet and one switch, limiting its usefulness beyond small networks.
• Cons: IPAM cannot assign addresses to devices, leaving address provisioning outside OpUtils.
• Cons: Paid plans are capped at 250 IPs each, a constraint for larger address inventories.

Alternatives

IP Address Management Software and Network Discovery Software collections can help compare products by category.

Subnetly is worth considering for a free monthly IPAM option with 256 addresses, 10 subnets, two DHCP pools, and private and public DNS zones. .NET offers a free plan for up to 1,000 nodes. GestióIP has free IPAM software and a configuration-management module for up to 50 devices at $400 a year. OpenNetAdmin, IPplan, and NIPAP are free options; OpenNetAdmin and NIPAP are open source, while IPplan is a self-hosted web application. Tidal LightMesh offers a free plan for one user and fewer than 1,000 IPs, with unlimited subnets, basic IPAM, and DHCP discovery. Amazon VPC IP Address Manager has a free tier for a single AWS region and account, including BYOIP IPv4 and IPv6 and public IP insights.

Verdict

Choose ManageEngine OpUtils if your team wants IP address tracking, switch-port visibility, network utilities, and security controls under one roof, particularly alongside Microsoft, Cisco Meraki, or ManageEngine systems. Its breadth and integrations are the main reasons to choose it. Look elsewhere if you need IPAM to assign addresses or the free edition to cover more than one subnet and switch.
