Thanks for your email.<br>
<br>
Kea has support for binding socket to unicast address of your
choice. It is documented in bind10-guide - section: 18.2.3. Unicast
traffic support.<br>
<br>
Also, the corresponding ticket about implementing this:
bind10.isc.org/ticket/3195<br>
<br>
Please, let me know if documentation is not sufficient or it doesn't
work as expected and doesn't solve the problem in your network.<br>

<div>Hi,</div>
<div><br>
</div>
<div>I’m writing to report a problem with bind10-dhcp6 component.</div>
<div><br>
</div>
<div>It seems like b10-dhcp6 only binds to ff02::1:2 (the local
dhcp multicast address) and the Link IPv6 address but *NOT* the
Global one.</div>
<div><br>
</div>
<div>See output of `ifconfig eth0` on my machine:</div>
<div><br>
</div>
<div>
<div>$ ifconfig eth0</div>
<div>eth0 Link encap:Ethernet HWaddr 00:02:C9:DD:0D:5E</div>
<div> inet addr:10.35.139.79 Bcast:10.35.139.255

<div> inet6 addr: fe80::202:c9ff:fedd:d5e/64 Scope:Link</div>
<div> inet6 addr: 2401:db00:3011:b:face:0:3b:0/64

<div><br>
</div>
<div>Here you can see it’s not binding on
2401:db00:3011:b:face:0:3b:0/64 (Scope:Global) as it should:</div>
<div><br>
</div>
<div>$ sudo netstat -tunap | grep dhcp6</div>
<div>udp 0 0 ff02::1:2:547 :::*
31292/b10-dhcp6</div>
<div>udp 0 0 fe80::202:c9ff:fedd:d5e:547 :::*
31292/b10-dhcp6 </div>
</div>
<div><br>
</div>
<div>The rack switches in our network are configured to relay
dhcpv6 traffic to the DHCP servers in our network via their
global IPv6 addresses.</div>
<div>Is this a known problem? </div>
<div>PS: I’m running a version of bind10 pulled from your git repo
HEAD on the 11th of February 2014.</div>
