IP address | IP address of the host.
MAC Address | MAC address of the host.
Interface | Interface to which the user belongs.
Reputation | Host's reputation score This column will only contain data when host reputation management has been enabled and the selected host is a monitored host.
Packets | Number of packets exchanged by the selected host.
Bytes in | Number of bytes that have passed through the firewall from the sending host ever since the firewall started running.
Bytes out | Number of bytes that have passed through the firewall towards the sending host ever since the firewall started running.

Continent | if the See all hosts (show hosts behind unprotected interfaces) checkbox has been selected in the filter, the source continent of the external host will be displayed.
Country | if the See all hosts (show hosts behind unprotected interfaces) checkbox has been selected in the filter, the source country of the external host will be displayed.
Reputation category | Indicates the external host's reputation category if it has been classified. Example: Spam, phishing, etc.

#### Right-click menu

Right-clicking on the name or IP address of a host opens the following pop-up menus:

- Search for this value in logs,
- Check usage of this host,
- Show host details,
- Reset this object's reputation score,
- Blacklist this object (for 1 minute, 5 minutes, 30 minutes or 3 hours),
- Add the host to the objects base and/or add it to a group.

#### Possible actions

Several search criteria can be combined. All of these criteria have to be met in order to be displayed, as the search criteria are cumulative.

This combination of search criteria can then be saved as a “filter”. Filters will then be saved in memory and can be reset in the Preferences module of the administration interface.

(Filter drop-down menu) | Select a filter to launch the corresponding search. The list will suggest filters that have been saved previously and for certain Views, predefined filters. Selecting the entry (New filter) allows the filter to be reinitialized by selecting the criteria selection.
Filter | Click on this button to: Select filter criteria (Search criterion). For the "hosts" view, the criteria are the following: By address range or by IP address By interface If the reputation score is higher than the value specified with the cursor. if the See all hosts (show hosts behind unprotected interfaces) checkbox has been selected, all hosts detected will be displayed in the table. Save as a customized filter the criteria defined in the Filter panel described in the next section (Save current filter). You can save a new filter using the button "Save as" based on an existing filter or a predefined filter offered in certain Views. Once a filter has been saved, it will be automatically offered in the list of filters. Delete current filter.
Reset | This button cancels the action of the filter currently in use. If it is a saved customized filter, this action will not delete the filter.
Refresh | This button refreshes data shown on the screen.
Export results | This button makes it possible to download a file in CSV containing information from the table. Once a filter is applied, all results matching this filter will be exported.
