DHCPv6 Confirm

Hello David,

Nothing special about my configuration, I think.  It seems rather basic.
For the link the tests were run on here is the subnet6 declaration:

subnet6 2001:558:ff10:0808::/64 {
        range6 2001:558:ff10:0808:0000:0000:0000:0000/64;

The only other note is that this seems to happen after the server receives 4
or more CONFIRM messages each from a unique client.  I will investigate some
more to see what else I can find.
