Cybera has confirmed that most Telus, some Shaw, University of Alberta users (via WiFi), and Concordia users have IPv6 connectivity. If you fall into one of these groups, please use the above links to verify and if at all possible, we ask that you use IPv6 to connect to your instance in order to help us conserve IPv4 addresses.
To help with connectivity, instances are also given an automated DNS name that maps to your IPv6 address and can be found on your instance's details page under the Metadata section.
IPv4 addresses are limited to 4.3 billion addresses and the world is quickly approaching the limit and obtaining new ones will become impossible. IPv6 uses 128-bit addresses instead of IPv4’s 32-bit addresses, removing this limit and providing better security features over IPv4. IPv6 is not a new technology as it has been available for over a decade, though it has been slow to implement due to legacy concerns across multiple industries.
As mentioned in the Accessing Instances section, connecting to an instance via IPv6 is preferred over using a Floating IP. Please see the links above to determine if you have IPv6 connectivity (Telus and University of Alberta users are known to have IPv6 connectivity). If you do have IPv6 connectivity, replace "
floating_ip_address" with your instance's IPv6 address in the instructions below. To determine your IPv6 address, instances are given an automated DNS name that maps to your IPv6 address and can be found on your instance's details page under the Metadata section.
