After working on a proposal for introducing IPv6 at work it suddenly dawned on me that pushing ipv6 at home wasn't going to work with a separate DNS zone for IPv6 addresses. The best way is to integrate ipv6 addresses in the main zone and have the "legacy ipv4 nat range" as second thing to try (for things that are still ipv4-only like nfs). But I found something weird in certain applications: for unqualified names, ipv4 is preferred, for qualified names ipv6. Forcing ipv6 works, but I want ipv6 to happen naturally. Telnet shows best what happens:$ telnet gosper
Trying 10.42.2.1...
Trying 2001:888:1011::694...$ telnet gosper.idefix.net
Trying 2001:888:1011::694...
Trying 82.95.196.202...Something weird happening here, so I asked the debian-ipv6 mailing list.
