IPv6 Support for SORACOM Arc

SORACOM Arc, a secure link service that allows compatible devices to connect directly to Soracom using any standard Internet connection, now supports connectivity using IPv6.

When configuring Arc, configuration details will be issued, which your device can then use to connect to Soracom. These configuration details include a connection endpoint which consists of a domain name like *.arc.soracom.io.

With this update, when your device looks up the domain name specified by the connection endpoint, both IPv4 (A record) and IPv6 (AAAA record) addresses will be returned:

$ nslookup abc.arc.soracom.io
Server:         192.168.0.1
Address:        192.168.0.1#53

Non-authoritative answer:
Name:   abc.arc.soracom.io
Address: 54.11.22.33
Name:   abc.arc.soracom.io
Address: 2406:d014:3333:4444:5555:6666:7777:8888

Your device can then use the IPv6 address to connect to Soracom.

Compatibility

In order for your device to connect using IPv6, both the device itself and all network elements between the device and Soracom must support IPv6. For example, if your device is connected via Wi-Fi to a router, the router must support IPv6 networking, and your Internet Service Provider must also provide you with an IPv6 address.

If you are using the soratun tool to configure and manage the SORACOM Arc connections on your device, you will also need to upgrade soratun to version 1.1.0 or later. You can check which version is currently installed by running soratun version.
