[atlas]IPv4 DHCP and varying addresses

Having a simple question regarding DHCP and varying addresses within a subnet... While I *do* have access to the config of the DHCP server that delivers addresses to 414, and thus the probe will always get that same IP address, I *do not* have access to configure the DHCP service in my ADSL CPE (yet), which means that the individual address given to the probe may change over time. I guess this is expected and being taken care of by the system, but wanted to double-check. Thanks, Wilfried.
