Abstract

Aspects of the subject disclosure may include, for example, a network device that accesses internet protocol addresses associated with a group of end point devices where the network device is a closest network device to the group of end point devices, and transmitting data to another network device responsive to a determination that an internet protocol address associated with the data from an end point device is one of the internet protocol addresses associated with the group of end point devices. Other embodiments are disclosed.
