Using the IP or Host Locator Tool 3-21
Discovering Nodes
Matching an IP Address to a Host Name
You can also use a known IP address to locate a device’s host name. To do so:
1. Click Clear to clear the default values from the IP and Host fields.
2. Enter the IP address of the device whose host name you wish to locate in the
IP or Full IP field.
3. If you wish to ping the device once its host name is located, click to select the
Ping found devices option; in the text field provided, specify a timeout
period, in seconds. If the device does not respond to the ping request within
the specified timeout, the ping will be considered to be unsuccessful.
4. Click on Update, or press Enter on the keyboard. If the IP address can be
resolved, its associated host name will be displayed in the Host field; if you
have selected the Ping option, a message window will indicate the success or
failure of the ping attempt. If the IP address cannot be resolved, a message
window appears, indicating that the selected IP could not be found.
Locating the MAC Address for a Host Name/IP Pair
Once you have resolved a host name/IP pair, you can use the Get MAC address button to
locate the device’s MAC address.
1. Enter an IP or host name in the appropriate field, and click Update to resolve
the pair.
2. Click on Get MAC address. The MAC address associated with the IP/Host
pair will be displayed in the text box to the right of the button.
You cannot use an IP or host name alone to retrieve a MAC address; you must first resolve
the pair to activate the Get MAC address button.
TIP
Once located, IP addresses can be copied (using the right-mouse edit menu or Ctrl-C on
the keyboard) and pasted (via Edit—>Paste) into the Insert Device window for addition to
the central node database. For more information about inserting devices individually, see
Chapter 4, List Views.
TIP
If you have a MAC address and wish to find the associated IP and/or host name, use the
MAC Search feature described in Matching a MAC Address to a Host Name and IP,
beginning on page 3-25.
