A note on applications
Some software applications contain IPv6 support, but it is not
turned on by default. This section contains basic instructions
on how to enable Mozilla Firefox and Mozilla Thunderbird to
lookup IPv6 addresses in DNS. The default setting in both is
to only look for IPv4 addresses.
Mozilla Firefox
1.In the Firefox address bar, enter the following:
about:config
This will bring up a complete list of configuration options for
Firefox.
2.Locate the option network.dns.disableIPv6, and set it
to false if it is not already.
Mozilla Thunderbird
1.In Thunderbird, go to Tools -> Options (for Mac, Thunderbird -> Preferences; for Linux, Edit -> Preferences).
7.Click the Apply Now button
To check if you have IPv6 connectivity, follow
these steps:
1.Open a terminal window (Applications -> Utilities ->
Terminal)
2.Type the following command:
ifconfig
This will cause the Thunderbird options window to be
displayed.
2.On the Advanced tab, click on the button labelled
Config Editor.
This will bring up a complete list of configuration options for
Thunderbird.
3.Locate the option network.dns.disableIPv6, and set it
to false if it is not already.
Having problems?
This will show your computer’s IP address information in the
terminal window. You should have at least one address:
This section contains some information about some of the
causes of potential problems when configuring IPv6.
e.g., “2402:6000:4000:4:”.
Sometimes it can appear that you have successfully connected to the wireless network even if you haven’t. Simply
disconnecting and reconnecting to the wireless network, or
turning your wireless card off and on may help.
3.Now, to see if IPv6 is working, type the following command into the terminal window:
ping6 www.apnic.net
If all goes well, you should see responses coming back from
www.apnic.net over IPv6.
• Does your computer use third party software to connect to wireless networks?
Sometimes there is third party wireless networking software
installed by the computer manufacturer. Often these third party
softwares don’t support IPv6, and don’t let your operating
system configure IPv6 itself.
