But it's not necessarily what people expect to occur. The vast majority of people don't realize that IPv6 is "on" by default on their OS, and that turning it on "on the router" will suddenly cause the email software to start using it. If you understand the components then the behavior makes sense - but people simply don't think of it.</div>
<div style><br></div><div style>In the case of the appliance I was referring to, there was no way to control or disable IPv6 (ie, you couldn't set a static address, even if you wanted to), so it was clearly a case of the appliance being broken. It basically fell into the same category as the above - the developers had just never considered that IPv6 was on by default, and it had never been a problem as IPv6 had never been enabled in their lab/test environments/etc.</div>
