I am confused about DHCP

[Antonio M]

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 192.168.0.63 after
192.168.0.62 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 %)
