This recipe configures your Raspberry Pi to support IPv6.
The Internet Protocol's sixth version, IPv6, is intended to replace the current IPv4 protocol. IPv6 provides 8x10^28 more IP address than IPv4. It is also a more stable, efficient, and secure protocol.
The majority of modern home network routers support both IPv4 and IPv6; however, not all of the older routers still in service support IPv6. So, IPv6 is not enabled by default on the Raspberry Pi, which saves a bit of memory and processing power. To take full advantage of modern networking services, you can enable IPv6 on your Raspberry Pi.
After completing this recipe, your Raspberry Pi will have IPv6 enabled.
