Comment 2 Jiri Belka 2017-10-30 15:47:45 UTC 
i did not have time to see if dns query is really done for A or AAAA record, but checking a dns server logs or tcpdumping traffic should reveal it.
Comment 3 Shyamsundar 2018-10-23 14:55:22 UTC 
Release 3.12 has been EOLd and this bug was still found to be in the NEW state, hence moving the version to mainline, to triage the same and take appropriate actions.

Status?
Comment 5 Amar Tumballi 2019-07-01 06:51:48 UTC 
With glusterfs-6.x and latest glusterfs branches we don't seem to have any IPv6 known issues. Considering this was opened with glusterfs3-12, would like to upgrade and see if this is fixed.

Marking it as WORKSFORME with higher versions.
