Enable IPv6.
If the system has IPv6 connectivity, query the DNS for IPv6 addresses as well
as IPv4 addresses. If IPv6 addresses are returned, prefer them by default.
Impact of this change:
- If the device is on a network with IPv6 configured, is using wifi, and has
obtained an IPv6 address using autoconfiguration, the network stack will
request IPv6 addresses as well as IPv4 addresses when making DNS queries. This
allows the device to connect to websites and services that declare themselves
to be reachable over IPv6. If an IPv6 connection fails, the stack will fall
back to IPv4. This is what Windows Vista, Mac OS 10.4 and above, and most
Linux distributions do by default.
- If the device is not on a network that supports IPv6, or is using 3G/EVDO,
nothing will change.
I have been testing this change on self-compiled builds of master and eclair on
Dream and Sholes for several weeks with no breakage that I can see.
