Can we disable IPV4 and use purely IPV6 on Windows XP/2003?

Solution 1:

Windows XP and Server 2003 share the same network stack (or at least major portions of it) which has some experimental IPv6 support, but not enough to use in production. Certainly not as a server. A few of the limitations:

• no DNS resolving over IPv6
• no IPv6 firewall
• not all applications use IPv6
• you can't configure addresses manually (important for servers)
• no DHCPv6 support
• No good IPv6 support in IIS

Especially because of the missing DNS resolving over IPv6 you will not be able to run a IPv6-only Windows XP or Server 2003 machine. I have run Windows XP in an 'almost-IPv6-only' environment. If you provide a local DNS resolver that speaks IPv4 then you can get basic web browsing to work.

But as far as I am concerned it's not worth the trouble...

Solution 2:

Go Properties on a network adapter. There is a list of protocols active on this adapter. Uncheck IPv4.
