 AS>> Win7 will definitely work better with this.

Indeed. Win7 is the best choice for now.

No, it's the default "prefer IPv4 over IPv6" in your system or browser 
settings.

For Firefox based browsers, check the following about:config settings:

network.dns.disableIPv6 = false
network.http.fast-fallback-to-IPv4 = false (Pale Moon with works for me with 
true though)

In case of WinXP, it's forced default behavior of "prefer IPv4" and there is a 
way to fix it by modifying netsh prefixpolicy as shown here:

 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

 MvdV> Indeed, that is a bit of a joke. Every IPv6 addres (2001:1c02::/32)

Is it dynamic or static? And if it's static, why your ISP can't provide a 
proper backresolve by customer request?
