Some hosting providers like scaleway allows to remove the IPv4 from the VPS in order to save 1€/month but doing this will result in losing connectivity to the "IPv4 world".
Or you may have ordered a VPS that only has IPv6 connectivity and you want to access to a resource only accessible from the "IPv4 world".
Here is how to gain your access back to the "IPv4 world".

Change your name servers(s) to DNS64 name servers(s)

Note: You may deploy your own DNS64 & NAT64 server on a separate server by following this tutorial (untested): https://packetpushers.net/nat64-setup-using-tayga/.
Note²: You may find a explanation of what is NAT64 and DNS64 on Wikipedia.

LTE-Cell-Scanner under Raspbian (and maybe Ubuntu/Debian)

Mark Jessop [email protected] 2017-11-19

Here in VK-land, GSM is dying, if not already dead in many parts of the country. As such, RTLSDR calibration tools like kalibrate-rtl are not particularly helpful! However, thanks (mainly) to Telstra, we have a very wide coverage 4G (LTE) network on 'Band 28', which is in a good frequency range for use with a RTLSDR (Downlink band 758 – 803 MHz). LTE-Cell-Scanner provides the 'CellSearch' utility, which will search for LTE cells, and determine the RTLSDR's clock offset. This gist attempt to provide some sort of guide on getting CellSearch running under Raspbian.
