IPv6 Servers

We have Windows Servers 2008 that are showing the Local Area Connection properties configured to enable IPv4 and IPv6.

How come when we ping such machines, sometimes the reply will say the Server's IPv4 address, and at other times it will say the Server's IPv6 address?

N-WConnect With a Mentor Commented:
By default, it will try to resolve the hostname to an IPv6 address first and if that is unsuccessful, it will fall back to resolving an IPv4 address.

You can force the ping to utilise either IPv4 or IPv6 by adding the parameters "-4" or "-6" to your ping command.
