**[Switch Port Mapper](https://www.manageengine.com/products/oputils/help/network/switch_port_mapper_tool.html)** : Utility to check and display the device connected to the ports of a remotely located Switch in real time network. The tool is useful for system and network engineers to gain visibility into the IP, MAC, status and availability of ports. Since this is a real-time discovery you can also view the operational status and port speed of each port. This tool maps switch ports to the devices connected to them.

**[IP Address Manager](https://www.manageengine.com/products/oputils/help/addressmgmt/ip_address_manager_tool.html)** : Utility to check for used, available and transient IP's in a given subnet or network. The tool helps manage the IP addresses in a static DNS environment, using pre-defined user policy. The tool scans a subnet and provides the availability status of IP addresses in that subnet. One can check whether a particular IP is reserved or available.

**[Rogue Detection](https://www.manageengine.com/products/oputils/help/addressmgmt/wireless_wired_rogue_detection_tool.html)** : Provides a list of rogue devices detected in the network.
