[atlas]DHCP behaviour of the probe on startup

Hi folks, while debugging some non-probe-related issues here at my ADSL'd net @home, I was told by the provider's techie, that the probe tries to grab *two* addresses at startup. He was monitoring the ARP table in the router, saw a DHCP request and the address assigned by the DHCP Server, and immediately asfterwards, the probe sent a request for an additional address, which was granted by the server. Trying to verify that, I later found out that I can ping the probe only on the second address.  Has anyone seen such a behaviour? Unfortunately, I don't have access to the router (cisco 800 series) as it is fully managed by the ISP, and for my other probe we had the IP-Address hard-wired into the DHCP server for the MAC address. Thanks, Wilfried.  this is particularly nasty for home networks with a very small number of addresses available (a bock of 8 in may case) and a long timeout...
