Uh, in this case, no it won't. A DNS server can contain and serve IPv6 RR types even if it has absolutely no IPv6 connectivity itself. What the log file shows are attempts to look up A and AAAA records. It happens that the machine being queried and the machine doing the querying could connect via IPv6, but that wasn't what the OP was complaining about. Honestly, this unthinking reflex advice to "turn off IPv6" is getting really tired, and it is not helpful. IPv6 is a fact of life. IPv4 address space is rapidly running out -- there's about 3 years worth to go. See this report, for instance: http://www.ripe.net/ripe/meetings/ripe-55/presentations/huston-ipv4.pdf If you aren't IPv6 ready and capable real soon now, then you're going to find it increasingly hard to cope on the Internet. On the other hand:= remember the Y2K feeding frenzy at the end of the 90's? There's going to be a similar scramble to switch to IPv6 and people with the requisite skills are going to be in demand...
