I'd consider that a bug worth of its own bugtracker entry. The address shouldn't change. I guess there's something wrong in the DHCP code that (receiving an ARP response,) it doesn't check whether it is started or not. Could you please file a bug report?

Thanks,
Simon

I dont want to submit this as a bug until others voice their ideas  based on their knowledge of DHCP and agree that it is.

I have built lwIP with DHCP enabled.  Im running in a static IP mode meaning dhcp_start wasnt called and netif_set_ipaddr is called with an address.  I have done this and connected on a network (with a DHCP server) that had a PC already at the same DHCPP assigned address as the static lwIP address.  I get the duplicate IP address bubble from Windows XP.  A few seconds later when I query my lwIP device to get its IP address, it has been changed to another IP address.

I would expect without calling dhcp_start that my devices IP address would not change.  It wont communicate, sure, but I dont expect it to be changed so that it can communicate unless I had called dhcp_start.  I do not know what happens if the PC is turned on second.  I can check that as well, but I think already the current behavior is not what it should be.

Thanks,

Bill
