Comment:

 According to
 [http://java.sun.com/j2se/1.5.0/docs/guide/net/ipv6_guide/index.html#ipv6-related]
 which also applies to Cyberduck:
  * By default, we would prefer IPv4 addresses over IPv6 addresses, i.e.,
 when querying the name service (e.g., DNS service), we would return IPv4
 addresses ahead of IPv6 addresses.

 To test IPv6 you therefore have to set the
 {{{java.net.preferIPv6Addresses}}} property to {{{true}}} in the
 Info.plist of Cyberduck.app/Contents.

 Using Passive FTP there may be problems connecting, as we do not currently
 support the IPv6 FTP extensions to parse a IPv6 address in response to
 {{{PASV}}}.
