Is ISC DHCP server will take dynamically changing value??

[ameen.shajahan at wipro.com]

My expectation is I have to change the subnet , lease range and lease time .
So that the client will get the changed subnet , lease range and its corresponding lease time.
In simple words, whenever the changes happened in conf file client can able to get the changes without restarting the server.
Can we able to do this kind of functionality using ISC code?
If ISC code allows to do the changes then how to proceed for that?
Please let me know

You want to change the subnet?

And what do you expect to happen with all those leases on the server
that were assigned in the old subnet?

And what do you expect to happen with all those leases on the clients
which have an active lease from the old subnet?
