## 8.3. Resolved Addresses

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:

1. Enable `Resolve Network Addresses` in the View → Name Resolution menu as this option is disabled by default.
2. Select `Use an external network name resolver` in the Preferences → Name Resolution menu. This option is enabled by default.

| Note
The resolved addresses are not updated automatically after a user changes the settings. To display newly available names, the user has to reopen the dialog.

The `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.
