One platform for DDI and switch port management

OpUtils is a unified DDI management solution designed for IT teams managing dynamic networks. It centralizes DNS, DHCP, and IP address management along with switch port mapping in a single, intuitive console. Whether it's a DNS misconfiguration causing resolution failures, an IP conflict disrupting a critical service, or inefficient DHCP scope utilization leading to address exhaustion, OpUtils provides the visibility and tools your team needs to quickly identify the root cause and resolve the issue before it impacts end users.

DNS management

Centralize DNS zone and record management across Microsoft DNS servers. Maintain accurate name resolution, eliminate stale records, and proactively detect lookup failures. Secure communication is enabled through WinRM.

Explore DNS management

DHCP management

Create and manage scopes, configure exclusions and reservations, enforce policies, and monitor multi-vendor DHCP environments including Microsoft, Infoblox, Cisco, and more, with alerts to prevent scope exhaustion.

Explore DHCP management

IP address management (IPAM)

Automatically discover and manage IPv4 and IPv6 addresses across your network. Advanced IP scanning detects conflicts, tracks utilization, and correlates IP data with DNS and DHCP for accurate addressing.

Explore IPAM

Switch port mapping

Get complete visibility into switch ports across your network, including Cisco ACI environments. Track real-time port status, discover connected devices, and map IPs, MACs, and VLANs to physical ports with automated port scanning.

Rogue device detection

Continuously scan your network for rogue devices. Classify devices as trusted, guest, or rogue, enforce DHCP MAC-based filters, and block access in real time to contain threats before they spread.

Loved by customers all over the world

“OpUtils is one of the best network monitoring and management software”

Reviewer Role: Mining & Metals

Company size: 1,001–5,000 Employees

I have been using this product for almost 8 years. Easy to use and manage and it has intuitive features and dashboard. I like the network tools and interface monitoring feature of the software and it compares configuration changes and it saves running as we as start-up configuration changes that is next level and the configuration backup schedule is way to much.

“Network monitoring, simplified”

Reviewer Role: Education Management

Company size: 11–50 Employees

It's a great tool to perform IP management and network monitoring. Easy to set up, navigate, and use. I can easily manage IP, devices connected switch ports. I use it to monitor the network for device intrusions and unusual IP activities.

“OpUtils is a great tool for small IT department”

Reviewer Role: Government Administration

Company size: 51–200 Employees

I use OpUtils to manage my IPs within my network. Primarily this is useful when certain networks have only static entries and it is harder to know what IPs are still available. Additionally, I have been able to use the Switch section to locate which port in the switch a device was plugged into. Ease to use is one of the best features. Additionally, the layout is fairly easy to understand. Cost and functionality were key factors in deciding to get OpUtils.

“Wonderful network switch port and IP address usage reporting”

Reviewer Role: Hospital & Health Care

Company size: 501–1,000 Employees

I am extremely happy that I found this product because I was having a lot of trouble keeping up with IP address usage and network switch port usage. There wasn't a solution that I knew of that could easily gather all of this information in one place. I didn't know there was a product that could integrate with DHCP servers and switches in such a way that it could easily report usage and availability. It is great at these items. Their support is wonderful and quick.
