OpUtils periodically queries the routers and subnets defined in the Router settings and collects the information, such as MAC Address, IP Address, and DNS Name of the devices and stores it in the database. The data is also updated whenever a scan is performed for a given IP range.
This data is presented in the form of a table showing the details of the collected information along with the time at which the data was updated.
Click on Toolset -> Address Monitoring.
Select the MAC IP List tab.
You can select to view the MAC-IP details of a specific subnet or search for a MAC or IP from the search box.
