The Resolved Addresses window shows the list of resolved addresses and their host names. Users can choose the
Hosts field to display IPv4 and IPv6 addresses only. In this case, the dialog displays host names for each IP address in a capture file with a known host. This host is typically taken from DNS answers in a capture file. In case of an unknown host name, users can populate it based on a reverse DNS lookup. To do so, follow these steps:
Resolve Network Addresses in the → menu as this option is disabled by default.
Use an external network name resolver in the → menu. This option is enabled by default.
The resolved addresses are not updated automatically after users change the settings. To display newly available names user have to reopen the dialog.
Ports tab shows the list of service names, ports and types.
Wireshark reads the entries for port mappings from the
hosts service configuration files. See Section B.3, “Configuration Files” section for more information.
