Client has not able to get IPv6 address??

[ameen.shajahan at wipro.com]

Hi all,
                I have tested the dhcpv6 server using ISC dhcp-4.2.3. while issuing ipconfig /renew from client side it shows the below output.
                Its not assigning IPv6 address to the client.
                Also there is a subnet declaration 3ffe:501:ffff:101::/64 in conf file.
                What could be the problem??
                Please let me know .
