What it does
ManageEngine OpUtils manages IP-address inventory, DNS/DHCP context and switch-port mappings for network administration.
Discover the configured IP ranges, subnets, DHCP servers or routers, then correlate IP, MAC and VLAN information with physical switch ports. OpUtils combines that inventory with DNS/DHCP context and conflict or utilization views; scheduled scans maintain the chosen scope. It is an on-premises product, with Microsoft DNS/DHCP integration through WinRM. Controls that change records, scopes or device access are separate administrative actions from inspection. The free edition covers one class C subnet and switch with limited management. Paid editions use managed IP and port counts, offer subscription or perpetual licensing, and have a 30-day trial.
