https://devzone.nordicsemi.com/f/nordic-q-a/6450/ping-icmp-ipv6-google-com-iotHi, I have the (IoT) environment running. The Raspberry Pi (with Miredo tunnel) is connected to the outside world. I can ping6 the ipv6.google.com server from Rasperry (terminal) with good result. Also I can ping6 two nRF bords (PCA10028) from theen-USTelligent Community 13Tue, 14 Apr 2015 11:35:02 GMThttps://devzone.nordicsemi.com/thread/22497?ContentTypeID=1Tue, 14 Apr 2015 11:35:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0b5b14c8-d905-4ab3-a2d7-1ee076c061f3Petter Myhre<p>Teredo gives your Raspberry Pi an IPv6 address that doesn&#39;t have a prefix, it is a unicast address.</p> <p>This means that you cannot share the address space further with Bluetooth Smart devices, since you only have one address given to you.</p> <p>This is mentioned in a note in the <a href="http://file:///C:/Keil_v5/ARM/Device/IoT%20SDK/Documentation/iot/html/a00035.html">IoT SDK documentation</a>.</p> <p>You need at least a /56 prefix, preferably a /48 prefix, so that you are able to give the whole /64 prefix to the Bluetooth Smart network.</p> <p>You could try <a href="http://en.wikipedia.org/wiki/6to4">6to4</a> with the script in the IoT SDK documentation.</p> <p>You need to insert the local IPv4 address of the Raspberry Pi in <code>ipv4_int=&quot;148.122.44.161&quot;</code></p> <p>A /48 prefix is created from the IPv4 address, see the wiki page for more information.</p> <p>Edit: Fixed global/local error</p><div style="clear:both;"></div>
