Host Discovery


    Host Discovery automatically populates the database with IP address, DNS Hostname, MAC address, response time and availability.

    Optionally with SNMP, you can maintain an accurate, up-to-date inventory of all your network equipment. You can populate the database with the serial numbers and software revision of all the routers and switches on your entire network.

    Typically, it takes less than 60 seconds to discover a full /24 subnet.

    Basic Configuration

    1. Select a subnet in the Subnet Tree.
    2. Go to Tools > Host Discovery in the toolbar.
    3. Click Add and choose Ping, DNS Hostname and SNMP from the dropdown list.
