A device may receive a request to establish a connection to a network device or one or more other network devices. The request may include a destination identifier that identifies a destination to which the request is to be provided. The one or more other network devices may be associated with a same Internet protocol (IP) address as the network device. The device may determine, from the destination identifier, a device identifier that identifies the network device or another network device as the destination to which the request is to be provided. The device may determine whether the device identifier matches a set of stored device identifiers. The device may provide the request to the network device or the other network device based on determining that the device identifier matches the set of stored device identifiers. The device may perform an action related to the request or the connection.
