ABSTRACT:
Generally speaking, systems, methods and media for detection and network reconfiguration upon changes in dynamic host configuration protocol (DHCP) IP addresses are disclosed. Embodiments of a method may include setting a renew time and a rebind time of a DHCP configuration and establishing an IP address with a first DHCP server. Embodiments may also include, after passage of the renew time, transmitting a renew request to the first DHCP server at its IP address and, in response to failure to receive an acknowledgement message from the first DHCP server, determining if the first DHCP server IP address is still valid. Embodiments may also include, in response to determining that the first DHCP server IP address is not still valid, retrieving a second, different DHCP server IP address from a network change event signal and configuring a network adapter based on the second DHCP server IP address.
