Right back in the year 2011, the last blocks of the IPv4 address space were allocated<\/a>. There were no new blocks left for any future expansion of the IPv4 address. This happened because more and more devices started connecting to the internet. It’s been exactly 10 years since 2011 and there have been many changes in the way ISPs operate. Carrier Grade NAT; A common solution adopted by many ISPs worldwide. Now, that allowed a common IPv4 address to be shared among a maximum of 128 network connected devices. CG-NAT is still not a long term solution to the problem, rather, a way to buy some time to roll-out IPv6. This tutorial teaches you how OpenWebRX, can be hosted with a public IPv6 address. <\/p>\n\n\n\n

Small changes in the program<\/h2>\n\n\n\n

Make sure to install OpenWebRX using the general installation guide<\/a> given on their github.com page. Make sure that your OpenWebRX installation works with localhost address. Now, we know that everything is working fine on IPv4. You shouldn’t proceed without getting it to work on IPv4. <\/p>\n\n\n\n

First file<\/h3>\n\n\n\n

Assuming that your OWRX to be working fine in your browser, open \/openwebrx\/owrx\/__main__.py<\/em><\/mark>. Add the following line after import signal<\/em>. <\/p>\n\n\n\n

import socket<\/pre>\n\n\n\n
Somewhere around line number 20 you will find class ThreadedHttpServer(ThreadingMixIn, HTTPServer)<\/em>.<\/p>\n\n\n\n
We need to change this class into the following:<\/p>\n\n\n\n
class ThreadedHttpServer(ThreadingMixIn, HTTPServer):\n    address_family = socket.AF_INET6\n    pass<\/pre>\n\n\n\n
Come right at the bottom of the file where you can find the “try:” <\/em>section. We need to modify the HTTP server instantiation to bind to a IPv6 socket. Replace the try <\/em>part of the code with the following code.<\/p>\n\n\n\n
try:\n        server = ThreadedHttpServer((\"::\", pm[\"web_port\"]), RequestHandler)\n        server.serve_forever()<\/pre>\n\n\n\n
Modifying the second file<\/h3>\n\n\n\n
In the same folder find socket.py <\/em>and open it with your text editor. We need to make amendments to very first line after function declaration.<\/p>\n\n\n\n
s = socket.socket(socket.AF_INET6, socket.SOCK_STREAM)<\/pre>\n\n\n\n
The code socket.AF_INET <\/em>works for IPv4. We changed it to socket.AF_INET6 <\/em>to make it work with IPv6 binding. <\/p>\n\n\n\n
