  Átgondolandó probléma ez.
  "One of the controversial IPv6 features in Windows Vista, Windows Server 2008, and Windows 7 is that it uses random interface identifiers when creating its IPv6 addresses. Typically, an IPv6-capable computer performs autoconfiguration with the Neighbor Discovery Protocol (NDP) to determine their network and interface identifier and form the computer’s 128-bit IPv6 address. The IETF’s RFC 2373 “IP Version 6 Addressing Architecture” describes in Appendix A how a computer should go about creating its EUI-64 based interface identifier using its MAC address. The IETF’s RFC 2464 “Transmission of IPv6 Packets over Ethernet Networks” describes in Section 4 how stateless address autoconfiguration should take place using a computer’s MAC address. Because of the privacy concerns about using hardware MAC addresses as interface identifiers the IETF created RFC 4941 “Privacy Extensions for Stateless Address Autoconfiguration in IPv6”. This RFC defines how an interface identifier can be created so that the privacy of the user can be preserved.

  Windows 7 doesn’t use the EUI-64 technique by default when forming its interface identifier. Microsoft has blurred the lines between these two address autoconfiguration concepts with their temporary addresses and now their randomly-generated interface identifiers. However, thankfully Microsoft has given us the ability to disable or enable this feature as needed with the following commands.

  netsh interface ipv6 set global randomizeidentifiers=disabled
  netsh interface ipv6 set global randomizeidentifiers=enabled

  There are a few things missing from Windows 7 that I was hopeful would be in this operating system by default. I was hoping to see Mobile IPv6 (MIPv6) support in Windows 7 because MIPv6 is not fully supported in Vista or Server 2008."

  Fej! Tor! Potroh!
