Hi All,
 
Is it possible for an server to change the network parameters at the renewal time.
 
I am trying to find out the desired server behaviour in some document but could not get it.
 
If the DNS/FTp or any other parameter is changed on the fly in server, then what the client is supposed to get which is already linked and is asking for a renewal.
 
I guess if the IP address is changed then the server should send the NAK. what about the parameters other than IP address.
 
I have seen some of the cllient which update the values only at the discover time and then just keep on renewing the lease without updating all the parameters.
 
 
is there any RFC that talk about the servers/client behaviour?
 
Thanks,
S.V.
