BAD ADDRESS after powercut

[MattDLEA]

can someone explane BAD ADDRESS ini DHCP to me. Or how to get rid of it.

 

We have a printer with a static address 10.72.240.103 this has been added as a reservation. After a powercut the printer reset to automatic ip which i have now restored to the original setting but i still have it showing as a bad address in DHCP?

BAD ADDRESS normally appears when you have two DHCP Servers setup in the same domain with Conflict Detection enabled. It's perfectly normal behaviour.

Bad Address basically means the following precess has occurred:

 

DHCP Client requests IP from DHCP Server

DHCP Server responds with an IP for the client

Client does an ARP lookup on the address and if it gets a response then it knows that address is in use. It then responds to the DHCP server to inform it that the IP is in use so it therefore wont try to hand it out again.

DHCP Client requests another address.
