    AS>> No, it's the default "prefer IPv4 over IPv6" in your system or browser   
    AS>> settings.   
    MvdV> Odd. Because this only happens when I use the RELAY6 method when locally   
    MvdV> accessing my website. When I used the netsh method, I always connected   
    MvdV> via IPv6. And wneh connected other websites aroud the world, IPv6 is the   
    MvdV> preferred method.   
      
   Then it's something with RELAY6 altering IPv6 default route priority.   
      
    MvdV> Hmmm...   
      
   Well, you can try this as cmd file (it's from that site, labeled as for WinXP)   
      
   echo Setting IPv6 loopback   
   netsh int ipv6 set prefixpolicy ::1/128 50 0 store=persistent   
   echo Setting Native IPv6   
   netsh int ipv6 set prefixpolicy ::/0 40 1 store=persistent   
   echo Setting IPv4   
   netsh int ipv6 set prefixpolicy ::ffff:0:0/96 35 4 store=persistent   
   echo Setting 6to4   
   netsh int ipv6 set prefixpolicy 2002::/16 30 2 store=persistent   
   echo Setting Teredo   
   netsh int ipv6 set prefixpolicy 2001::/32 5 5 store=persistent   
   echo Setting ULAs   
   netsh int ipv6 set prefixpolicy fc00::/7 3 13 store=persistent   
   echo Setting v4compat   
   netsh int ipv6 set prefixpolicy ::/96 1 3 store=persistent   
   echo Setting IPv6 site-local   
   netsh int ipv6 set prefixpolicy fec0::/10 1 11 store=persistent   
   echo Setting 6bone   
   netsh int ipv6 set prefixpolicy 3ffe::/16 1 12 store=persistent   
   rem Show results   
   netsh int ipv6 show prefixpolicy   
   pause   
      
   ...or you can experiment with such settings by yourself (highest priority   
   value is used as most preferred)   
      
    AS>>>> ipv6.dynamic.ziggo.nl [2001:1c02:1100:d700:f1d0:2:280:5555]   
    AS>>>> but your ISP does not seem to assign proper reverse DNS for   
    AS>>>> customers.   
    MvdV>>> Indeed, that is a bit of a joke. Every IPv6 addres   
    MvdV>>> (2001:1c02::/32) of my provider backresolves to   
    MvdV>>> ipv6.dynamic.ziggo.nl.   
    AS>> Is it dynamic or static?   
    MvdV> Dynamic.   
      
   So it is set automatically by ISP and changes every time you reconnect? Then   
   how did you set it to f1d0-style?
