-If your operating system includes IPv6 support, ethereal will attempt to
-use reverse name resolution capabilities when decoding IPv6 packets. If
-you want to turn off name resolution while using ethereal, start ethereal
-with the "-n" option. If you would like to compile ethereal without
-support for IPv6 name resolution, use the "--disable-ipv6" option with
-"./configure". If you compile ethereal without IPv6 name resolution,
-you will still be able to decode IPv6 packets, but you'll only see IPv6
-addresses, not host names.
+If your operating system includes IPv6 support, wireshark will attempt to
+use reverse name resolution capabilities when decoding IPv6 packets.
+
+If you want to turn off name resolution while using wireshark, start
+wireshark with the "-n" option to turn off all name resolution (including
+resolution of MAC addresses and TCP/UDP/SMTP port numbers to names), or
+with the "-N mt" option to turn off name resolution for all
+network-layer addresses (IPv4, IPv6, IPX).
+
+You can make that the default setting by opening the Preferences dialog
+box using the Preferences item in the Edit menu, selecting "Name
+resolution", turning off the appropriate name resolution options,
+clicking "Save", and clicking "OK".
+
+If you would like to compile wireshark without support for IPv6 name
+resolution, use the "--disable-ipv6" option with "./configure". If you
+compile wireshark without IPv6 name resolution, you will still be able to
+decode IPv6 packets, but you'll only see IPv6 addresses, not host names.
