strange message

[Barbara Nowak]

Hi,
 
I use dhcp with MAC addresses (not dynamic range), and sometimes I receive strange message in my logfile:
 
Aug 21 10:49:26 srv dhcpd: DHCPREQUEST for 172.24.4.41 from 00:50:fc:fe:21:3e via eth1
Aug 21 10:49:26 srv dhcpd: DHCPACK on 172.24.4.41 to 00:50:fc:fe:21:3e via eth1
 
Aug 21 11:32:29 srv dhcpd: DHCPINFORM from 172.24.4.41 via eth1
Aug 21 11:32:29 srv dhcpd: DHCPACK to 172.24.4.41 (<no client hardware address>) via eth1
 
What exacly above 2 lines means? I had only 2 clients with these messages. Others works OK.
