Example - Enabling IPv6 on Windows XP/2003/Vista
By default, Windows XP and Windows 2003 support IPv6. This example shows you how to use the
ipv6 install
command on Windows XP/2003 to enable IPv6. This also displays how to use the
ipconfig
command to see auto-generated IP addresses.
IPv6 is installed and enabled by default in Windows Vista. Use the
ipconfig
command to check
your automatic configured IPv6 address as well. You should see at least one IPv6 address available
for the interface on your computer.
Example - Enabling DHCPv6 on Windows XP
Windows XP does not support DHCPv6. If your network uses DHCPv6 for IP address assignment,
you have to additionally install a DHCPv6 client software on your Windows XP. (Note: If you use
static IP addresses or Router Advertisement for IPv6 address assignment in your network, ignore
this section.)
This example uses Dibbler as the DHCPv6 client. To enable DHCPv6 client on your computer:
1
Install Dibbler and select the DHCPv6 client option on your computer.
2
After the installation is complete, select
Start

Now your computer can obtain an IPv6 address from a DHCPv6 server.

Windows 7 supports IPv6 by default. DHCPv6 is also enabled when you enable IPv6 on a Windows 7
computer.
To enable IPv6 in Windows 7:
1
Select

different one, if you like.
Protocol
: This is the type of IP protocol used by the service. If this is
TCP/UDP
, then the service
uses the same port number with TCP and UDP. If this is
USER-DEFINED
, the
Port(s
) is the IP
protocol number, not the port number.
Port(s)
: This value depends on the
Protocol
.
If the
Protocol
is
TCP
,
UDP
, or
TCP/UDP
, this is the IP port number.
If the
Protocol
is
USER
, this is the IP protocol number.
Description
: This is a brief explanation of the applications that use this service or the situations
in which this service is used.
