[Dnsmasq-discuss] Strange dhcp behavior, Problem assigning particular ip's

[Peter Katzmann]

Hello,
i have here a d-link printbox. This should change from static to dhcp ip.
Normally the box has the ip 192.168.2.252 and the hostname druckserv3

When i configured a dhcp-host entry with ,mac,hostname
i receive the following messages:
  DHCPDISCOVER(eth0) 00:80:c8:bd:ac:d8
  DHCPOFFER(eth0) 192.168.2.252 00:80:c8:bd:ac:d8
  DHCPREQUEST(eth0) 192.168.2.252 00:80:c8:bd:ac:d8
  DHCPNAK(eth0) 192.168.2.252 00:80:c8:bd:ac:d8 lease not found

The same with ip 192.168.2.251

But strangely with 192.168.2.250 it works:
DHCPDISCOVER(eth0) 00:80:c8:bd:ac:d8
DHCPOFFER(eth0) 192.168.2.250 00:80:c8:bd:ac:d8
DHCPREQUEST(eth0) 192.168.2.250 00:80:c8:bd:ac:d8
DHCPACK(eth0) 192.168.2.250 00:80:c8:bd:ac:d8 Drucksrv3

Well, this ip and the entry is unique, a Xerox Phase with .253 works 
perfectly.

Any clues ? or hints how to debug this problem ?

Thanks
