debian IP address same as server


Hi all,

My problem is when I installed debian, there was an IP conflict between debian and the server(which already had the IP reserved), but this server isn't the DHCP server. I don't understand why debian was assigned the same IP on the network if it's already taken? Debian was set to dynamic until I changed it to static to resolve this conflict. My manager doesn't want the machine to be static, he wants it dynamic. If I change it back to dynamic, I'm sure it will be set to the same IP as the server, again. Can anyone tell me why the debian machine is assigning the same IP as the server even if it's already taken?

Thanks in advance

Mike

When you say "already had the IP reserved", what do you mean by that?

DHCP servers have a range of addresses they assign. If someone manually assigns an address from that same range to a system, the DHCP server wouldn't know it. Then the DHCP server might assign that same, overlapping address.

The thing is that one of the servers was assigned an IP address(static), but what I found out was that on the DHCP server, that IP wasn't assigned/reserved to that particular server.

Thanks cyclepathology, you answered my question, I now understand what happened and you're right!
