[7.904][NOTABUG][CLOSED] DNS performance

RFCat_vk_01
Hi,
I have noticed that most of the time during the beta testing that the DNS is extremely slow. Too many DNS timeouts.
Now my users are complaining about sites that did work, that don't anymore.

    if your isp doesn't support ipv6 then youa re going to have this issue.  comcast(my isp) only supports ipv6 in limited markets..so enabling it in astaro causes these kinds of issues.   I had to rmeove ipv6 resolution from my client's dns server on several occasitons already...you will most likely ahve to do the same for yours. I would disable ipv6 on your astaro OR use a non ipv6 dns server and talk to your isp.
