Version 6 Question: Client trying to get new parameters

[Gernot Riegert <[e-mail]>]

Hello folks,

In the latest draft concerning DHCPv6 the way to reconfigure at least one 
DHCP client is that the server sends a DHCP Reconfigure message to the 
host(s) with the parameters that have to be changed.

But what if a client states that some of its parameters aren't valid 
anymore? In the draft, I don't see how a client can ask for a new 
configuration if the old one doesn't "fit" any more besides cancelling 
his connection. So, the client is urged to start a new configuration 
process, which is rather superfluous in my oppinion. 

A second question: In the description of the DHCP Release message, it is 
said that a client might want to release ressources it doesn't need 
anymore. What ressources are meant with these words? Could someone give 
me an example?
 

Thank you for your help
