WinXP supports privacy extension. It is on by default. But there is also the SLAAC address. If PE is enabled, it will use the PE address for outgoing connections. But the machine will always answer to the static address as well.

The address ending in 213d is the SLAAC address derived from the MAC address of the interface. The other is the PE address that changes every 24 hours:
