I have a small LAN with DHCP running on Fedora 9. I checked the active leases: this is the list of active leases 1)I don't understand how IP address is connected to MAC address, i.e. if a MAC has already an IP address, should a new lease be started with same MAC address?? I see 5 IP's connected to same MAC address 2) How are the IP adressess released?? I would expect <a href="http://192.168.0.63">192.168.0.63</a> after <a href="http://192.168.0.62">192.168.0.62</a> and so on... (please note that 00:16:d4:dc:a7:08 sometimes is started by F9 and sometimes by F10 200 IP addresses available, 6 allocated (3 %) IP Address Ethernet Hostname Start Date End Date <a href="http://192.168.0.62">192.168.0.62</a> 00:16:d4:dc:a7:08 acer 2008/06/11 07:07:52 2008/06/18 07:07:52 <a href="http://192.168.0.224">192.168.0.224</a> 00:16:d4:dc:a7:08 2008/06/12 06:39:18 2008/06/19 06:39:18 <a href="http://192.168.0.155">192.168.0.155</a> 00:1a:80:23:e3:7b PC-contecsrl 2008/06/12 07:03:23 2008/06/19 07:03:23 <a href="http://192.168.0.158">192.168.0.158</a> 00:16:d4:dc:a7:08 2008/06/13 07:47:01 2008/06/20 06:50:47 <a href="http://192.168.0.241">192.168.0.241</a> 00:16:d4:dc:a7:08 2008/06/13 07:22:33 2008/06/20 07:22:33 <a href="http://192.168.0.90">192.168.0.90</a> 00:16:d4:dc:a7:08 2008/06/13 07:47:01 2008/06/20 07:47:01 <a href="http://192.168.0.155">192.168.0.155</a> 00:1a:80:23:e3:7b PC-contecsrl 2008/06/13 07:50:57 2008/06/20 07:50:57 -- Antonio Montagnani Skype : antoniomontag
