This disclosure describes systems, methods, and apparatus related to receiving, at an access point and from a wireless communication station, a media access control (MAC) address of the wireless communication station; assigning, at the access point, a prefix to the MAC address of the wireless communication station; receiving, at the access point and from the wireless communication station, a frame comprising the prefix and a random MAC address; replacing, at the access point and using the prefix, the random MAC address in the frame with the MAC address of the wireless communication station, thereby resulting in a processed frame; and transmitting, at the access point and to a destination device, the processed frame.

A method, computer program product, and computing system for generating one or more unique network addresses for one or more storage array enclosures of a storage system. The one or more unique network addresses may be advertised to one or more storage processors of the storage system. The one or more storage processors may be configured to communicate with a plurality of storage devices of the one or more storage array enclosures based upon, at least in part, the one or more unique network addresses of the one or more storage array enclosures.

A network system including a plurality of devices can acquire authenticated location information of a device and provides various services using the authenticated location information. Each of the plurality of devices includes: a communication unit for performing data communication with another device; a storage unit that stores a digital certificate including a public key for determining an IP address of the device; and a determination unit that determines an IP address of another device based on a public key included in a digital certificate received from the another device. The digital certificate includes location information associated with a corresponding device.

Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of a first wireless device including processing circuitry configured to decode a first data frame from a second wireless device, the data frame indicating a destination address of a third wireless device and in response to the third wireless device being an immediate neighbor of the first wireless device, encode a second data frame comprising the data from the first data frame and an address of the third wireless device as the receiver address of the data frame. The processing circuitry further configured to in response to the third wireless device not being an immediate neighbor of the first wireless device, encode the second data frame to comprise the data from the first data frame, an address of a fourth wireless device, and the address of the third wireless device.

Techniques are described for analyzing information network traffic to identify distinct devices connected to a network based on characteristics exhibited by the devices. Techniques may analyze some or all of network characteristics, device behavioral patterns, and/or device characteristics detected in network traffic. One or more of these characteristics, may be assigned to a profile associated with a device. This profile, by establishing one or more patterns of behavior and/or characteristics, may be used as a “fingerprint” to uniquely identify a device connected to a network even for devices that employ randomized identifiers, such as MAC addresses, that would otherwise obscure unique identification of the device. Profiles exhibiting similar patterns of behaviors and/or characteristics may be identified and merged to avoid duplicate identification of a same device.

Embodiments of this application disclose a domain name system server determining method, and a request processing method, apparatus, and system. An embodiment of this application provides a domain name system server determining method, including: A session management function network element determines an address of a first domain name system server based on a first location of user equipment, where the first domain name system server is a local domain name system server that resolves a domain name of a first application into a corresponding first Internet protocol address, which is associated with the first location; and the session management function network element sends the address of the first domain name system server to a first device.

A technique that manages device addresses involves: sending, at a first device, a probe message to at least one other device, wherein the probe message includes a first MAC address of the first device, a first identifier of the first device, and an IP address to be assigned to the first device; receiving a message from a second device, the message including a second MAC address of the second device, a second identifier of the second device, and an IP address of the second device; and according to a determination that the IP address of the second device is the same as the IP address to be assigned to the first device, providing a probe alert including the identifies and indicating that an IP address conflict occurs. By writing device IDs in messages transmitted across a network, devices that may have an IP address conflict can be quickly detected.

Some embodiments provide a novel method for assigning a unique internet protocol version 6 (IPv6) link-local address to each interface of a software router implementing a plurality of logical interfaces for a corresponding plurality of logical networks. In some embodiments, the method, for each logical interface, determines a logical network identifier for a logical network corresponding to the logical interface and generates the link-local address based on that logical network identifier (e.g., a virtual network identifier (VNI)).

A method for detecting an IPv6 aliased prefix based on fragmented fingerprint includes: generating a plurality of pseudo random addresses in a target prefix space; determining the target prefix as an active prefix; and determining that the plurality of the pseudo random addresses and the active prefix are configured on the same host, so as to identify the active prefix as the aliased prefix. This method may effectively discover a network host, reduce the cost of network detection, and provide more effective data support for network measurement, network surveying and mapping and security research.

A method for data communication and computation over a network whereby nodes of the network are capable of evaluating functions in the local environment of the node, and where the addresses of newly created or of newly connected network nodes are assigned at random, near uniqueness of node addresses being accomplished by using a random or pseudo-random method of choosing one address from a sufficiently large pool of network addresses.
