DHCP server not reasigning IPs

Question

Hello everyone,
We're having a big issue with our DHCP server (MAC OS X Server 10.6.4), because it runs out of IPs, because it's not reasigning the same IP to the same device.
The file /var/db/dhcp_leases show me the same MAC address and different IP, not freeing the anyone and thus, causing the server to stop giving IPs. We've currently managed to make a script to delete the leases db daily, but some days it's nt enough, any advise you could give us?
Some of the dchp_leases file:
ip_address=10.1.0.182
hw_address=1,0:26:bb:55:c4:e2
identifier=1,0:26:bb:55:c4:e2
lease=0x4cbda154
ip_address=10.1.0.181
hw_address=1,0:1b:63:b5:6a:de
identifier=1,0:1b:63:b5:6a:de
lease=0x4cbda0a3
name=MAC265
ip_address=10.1.0.180
hw_address=1,c4:2c:3:32:2d:23
identifier=1,c4:2c:3:32:2d:23
lease=0x4cbd9fe3
name=MAC265
ip_address=10.1.0.179
hw_address=1,c4:2c:3:32:2d:23
identifier=1,c4:2c:3:32:2d:23
lease=0x4cbd9f27
name=iPod
ip_address=10.1.0.178
hw_address=1,90:84:d:c4:72:2e
identifier=1,90:84:d:c4:72:2e
lease=0x4cbd9d08
Thanks in advance,

This looks more like a problem with network settings and not any hardware problem. Try to setup your LAN connection again. Recheck your network service provider settings (thru default access page 192.xxx.xxx.xxx, using wireless connection): check whether DHCP server is enabled.
If you are using mac address filter, add mac address of your LAN card to the allowed addresses in network settings in 192.xxx.xxx.xxx
