Does my device support IPv6?
Most devices nowadays are dual stack, that is, they support both IPv4 and IPv6. The choice of whether IPv4 or IPv6 is used largely depends on the operating system. Newer versions of Windows and Linux default to preferring to use IPv6 unless otherwise specified.
Do I need to change anything?
Because UBC has not migrated to IPv6, network adapters should be configured to use IPv4. The following websites provide general information on how to configure your device to prefer IPv4:
- Windows Resources
- On Windows devices, the preference would be configured at the network adapter level.
- Windows FAQ on IPv6
- Check out this Microsoft KB 929852 on how to prefer IPv4 over IPv6.
- Mac Resources
- UNIX Resources
When I issue a ping, I receive an IPv6 response.
Some ping utilities have been changed to default to using IPv6. You may have to issue arguments in order to ping over IPv4. On Microsoft Windows, for example, issue ping <hostname> -4
I am seeing IPv6 DNS responses to queries when querying *.ead.ubc.ca.
EAD hosts its own DNS and EAD is the SOA for the ead.ubc.ca namespace. This means that myDNS will forward any requests to EAD DNS servers for the ead.ubc.ca namespace. By default, any connected EAD clients will use Dynamic DNS (DDNS) to register their IP addresses (both IPv4 and IPv6) into the EAD DNS servers. IPv6 is disabled on UBC's domain controllers, however, both IPv4 and IPv6 records exist in EAD DNS.
Where can I get more information on IPv6?
There are many websites providing info on IPv6. Visit World IPv6 Launch for statistics on IPv6 uptake.
