IPv6 kerenl mechanism

Hello,
I have an IPv6 application that needs to be told when the 2.6.11 kernel has
accepted a router announcement prefix and has inserted that address into the
appropriate interface.  This application will then set up and do the
necessary binds to set up the tcp/ssh listen addresses correctly. 
 
Is there any code in place in the kernel that an application can key on to
know when a new IPv6 address has been accepted from  the router or if a user
has issued the "ip -6 addr add" or "ip -6 addr del" command?

Thank you,
Phil Bellino
