ManageEngine OpUtils

Overview

ManageEngine OpUtils is a network management suite for keeping track of IP resources and network devices. It is best suited to administrators who want IP address management, switch-port visibility, diagnostics, and security controls in one toolset. Its range is useful, but the free edition is limited and its IPAM cannot assign addresses to devices.

Key features

OpUtils pairs IP address management with switch-port mapping, giving teams a way to track address space and see which devices are connected to switch ports. Its DDI management combines DNS, DHCP, and IP address management, including Microsoft DNS and DHCP. It can monitor Microsoft DHCP scopes and leased addresses, but cannot assign IP addresses to devices. That makes it a weaker fit for teams expecting IPAM to handle address provisioning as well as monitoring.

More than 30 network utilities cover diagnostics, SNMP, Cisco, address monitoring, and connectivity. Rogue-device detection, IP-conflict and ARP-spoofing alerts, and DHCP MAC-based filtering add useful safeguards for networks where unauthorized devices or address conflicts are a concern. Role-based access control and two-factor authentication provide additional access controls.

Integrations include Microsoft DHCP and DNS, Cisco Meraki controllers, and ManageEngine products such as OpManager and NetFlow Analyzer. APIs can connect OpUtils to third-party IT management and service desk software, which helps fit it into an existing operations workflow. Phone support runs 24 hours a day, Monday through Friday.

Pricing

OpUtils has a free edition, paid plans, and a 30-day trial. The free plan costs nothing and supports one Class C subnet and one switch, with basic IP and network scanning. That cap makes it suitable for a small company evaluating the tool or managing a very small network, but it is unlikely to cover a larger environment.

Professional is priced on request and includes 250 IPs, switch ports, IP address management, switch-port mapping, rogue-device detection, and 30+ network tools. It suits teams focused on IPAM and port visibility without the full DDI scope. Management is priced on request and adds full DDI management to the same stated 250-IP allowance, switch-port coverage, mapping, detection, and tools. That is the better fit for teams that need DNS and DHCP management alongside IPAM. Both paid plans retain the same stated 250-IP limit, so the choice is principally about DDI coverage.

Platforms

OpUtils is available as downloadable software for 64-bit Windows and Linux, with browser access. Its mobile app for iOS and Android supports monitoring network addresses and ports. The platform offering also includes an API, useful for integrations with other IT and service desk systems.

Who it's for

OpUtils is a strong candidate for network administrators who need address-space oversight, switch-port mapping, diagnostics, and security checks together, particularly in Microsoft DNS and DHCP or Cisco Meraki environments. Small companies can start with the one-subnet, one-switch free edition. Teams that need address assignment through IPAM should look elsewhere, as should organizations whose IP needs exceed the paid plans' stated 250-IP allowance.

Pros and cons

• Pros: Combines IPAM, switch-port mapping, DDI management, and more than 30 network tools, reducing the need to assemble those capabilities separately.
• Pros: Rogue-device detection, IP-conflict and ARP-spoofing alerts, and DHCP MAC filtering address practical network security concerns.
• Pros: Browser, Windows, Linux, iOS, and Android access support a mix of desktop and mobile workflows.
• Cons: IPAM cannot assign device addresses, leaving a gap for teams that want provisioning as part of address management.
• Cons: The free plan's one Class C subnet and one switch cap limits its usefulness beyond small networks.
• Cons: The paid plans each state a 250-IP allowance, which may constrain larger deployments.

Alternatives

IP Address Management Software is a useful category comparison for buyers weighing dedicated IPAM choices; Network Discovery Software is the better starting point when discovery is the main requirement.

Subnetly is worth considering for teams looking for a free tier with 256 IPAM addresses, 10 subnets, DHCP pools, and DNS zones; it lists API, iOS, Linux, web, and Windows platforms. Tidal LightMesh fits buyers who prefer a free basic IPAM tier for one user and fewer than 1,000 IPs, with unlimited subnets and DHCP discovery, or a Pro monthly plan at $35 a month.

GestióIP offers free IPAM software and a configuration-management module for up to 50 devices at $400 per ye, making it an option for buyers comparing a free software base with a separately priced device module. .NET lists a free plan for up to 1,000 nodes and may suit readers whose requirement matches that node-based offer.

Azure IPAM is a free, open-source project for Azure infrastructure, though Azure infrastructure and hosting costs are separate. IPplan is a free GPL self-hosted web application; NIPAP is a free open-source option under the MIT license; and OpenNetAdmin is a free open-source IPAM system.

Verdict

Choose ManageEngine OpUtils if your team wants IPAM, switch-port mapping, diagnostics, and network safeguards in one suite, with browser and mobile access and useful Microsoft and Cisco integrations. Its clearest weakness is that IPAM does not assign addresses, while the free edition is too narrowly capped for many growing networks. Teams needing address provisioning or a higher stated IP allowance should compare alternatives before committing.
