Description (last modified by xfk)

A tcpdump shows that twisted only sends A? requests before throwing a DNS lookup error.

With adding IPv6Address in the list on the following line twisted also looks for AAAA records and successfully finds them:

Altough it finds the the correct AAAA record is found with the modification above (looking at tcpdump), it never tries to connect to the returned address and only giving the following error: An error occurred while connecting: -9: Unknown error -9.

What you really want to be doing here is using HostnameEndpoint rather than calling this directly.

This is a duplicate of #10062. There is a PR associated with #10062 (PR #1488) though it seems to have stalled out --- a fresh attempt would be welcome.

Tom, are you sure this is a duplicate of #10062? My reading is that #10062 is complaining about the use of ANY? lookups, while this one refers to a different bit of code, which doesn't do ANY? lookups (but also doesn't do AAAA? lookups).
