[curl:bugs] #1274 IPv6 DNS requests were sent out from Android Handsets even if the IPv6 stack is not present on the device.

Plain old getaddrinfo() is getting called as seen in the log.

To me this seems like a bug in Android's (bionic's?) getaddrinfo() implementation and not in libcurl. Do you think otherwise?

Have you compared to how getaddrinfo() acts if you do the same on a glibc Linux system without ipv6 enabled?

"no IPv6 stack on the device" you say, is that really true? Surely they didn't rip out the IPv6 parts from the Linux kernel on your device?

Observation:
IPv6 DNS requests were sent out from Android Handsets even if the IPv6 stack is not present on the device.
Expected Result:
If there is no IPv6 stack on the device/machine, the IPv6 request should not be sent from the device.
Workaround:
Using option "CURL_IPRESOLVE_V4", disables sending IPv6 DNS queries.
Libcurl details:
OS: Linux - Android
