Abstract: Methods and systems are described for assigning the proper internet protocol (IP) address to a client device following authentication of the client device on a network. In particular, at commencement of an authentication procedure of the client device, a role is associated with the client device that denies all DHCP renews/requests. By assigning a role to the client device 103 with a “deny DHCP renew/request” rule at the commencement of an authentication procedure, the systems and methods described herein ensure that a race condition does not allow the client device to renew an IP address in an old segment of the network. Accordingly, the client device may avoid a possibly improper IP address in a segment of the network system in which the client device is no longer associated with or operating on.
