Most of these caveats are really with the software specified and not IPv6 itself:
- Windows XP natively supports IPv6, but it does not provide its IPv6 address to DDNS and cannot use IPv6 for file sharing, remote desktop or name resolution transport.
- Windows Server 2003 natively supports IPv6, but it cannot use IPv6 for file sharing, terminal services or DNS transport.
- There is no general-purpose IPv6-to-IPv4 or IPv4-to-IPv6 translator, although application-specific proxies like multihomed DNS resolvers and web proxies can be implemented
