A residential gateway to facilitate network access to a network, comprises at least one processor and at least one memory. The at least one memory stores instructions that, when executed by the at least one processor, cause the residential gateway to: communicate packet data for IP services being provided to an end user device and the network, the end user device having been assigned an IP address based on a first IP prefix assigned to the residential gateway; receive a second IP prefix assigned to the residential gateway; and notify the end user device that the IP address assigned to the end user device is no longer valid based on receipt of the second IP prefix.
