Shared networks and range priority

[Enrico Demarin (home)]

Hi Everyone,

I am running a shared network configuration where i have a pool of 
public routable addresses  and a pool of private addresses, and I am 
wondering if it's possible in any way to define the priority which the 
dhcp server will use in offering these addresses.
Given the configuration below, is it possible in any way to have the 
dhcp server assign  the addresses from the 48.37 network  first and 
begin assigning the addresses of the 10.1 subnet last ?

example:

shared-network shared_eth1 {

subnet 10.1.0.0 netmask 255.255.0.0 {
option routers                  10.1.0.1 ;
option subnet-mask              255.255.0.0 ;
option domain-name-servers      4.2.2.1 , 4.2.2.2 ;
range dynamic-bootp     10.1.200.200 10.1.200.220 ;
default-lease-time 3600 ;
max-lease-time 3600 ;
}

subnet 48.37.115.0 netmask 255.255.255.0 {
option routers                  48.37.115.1 ;
option subnet-mask              255.255.255.0 ;
option domain-name-servers      4.2.2.1 , 4.2.2.2 ;
range dynamic-bootp 48.37.115.10 48.37.115.70;
default-lease-time 3600;
max-lease-time 3600 ;
}

}


thanks in advance
