Broadcast flag: broadcast or unicast

I am seeing weird behavior in our network. any end device which is trying to renew IP address sends a Request packet with a Broadcast flag as Broadcast is unable to renew IP address.

any client that is sending it as Broadcast flag as Unicast is able to renew the lease.


since they are not able to renew ip they will keep sending request packets until the lease is expire and then start the discovery process to renew the lease.
