Methods, systems, and devices relate to digital wireless communication, and more specifically, to techniques relating to dynamic change MAC address of the station for subsequent transmissions. In one exemplary aspect, a method of dynamic change MAC address includes specifying a MAC address change mode and a new MAC address to be used by the station. In another exemplary aspect, a method of dual MAC address change mode in the dynamic change MAC address mechanism includes separating the unchanged MAC address of the station from the changeable MAC address of the station, and keep the mapping between them. In another exemplary aspect, a method includes transmitting a MAC address change request message from the station (or the access point) to initiate the MAC address change procedure. In another exemplary aspect, a method includes receiving a MAC address change response message from the access point (or the station).

A system and method for internet numbers management is provided. Historical internet protocol (IP) block information associated with a plurality of IP blocks is received from a server database. The historical IP block information includes IP block size information and IP block type information. A machine learning model is trained based on the historical IP block information. Predictions are received from the trained machine learning model indicating a pool of IP blocks of the plurality of IP blocks to be audited. An electronic action is generated to obtain validation status information for each IP block of the pool of IP blocks. The historical IP block information in the server database is updated with the validation status information for each IP block of the pool of IP blocks.

In one embodiment, a method includes receiving a plurality of uniform resource identifiers (URI's) associated with a particular domain. Each of the URI's identifies a content page comprising one or more signature elements. The method further includes, for each URI in the plurality of URI's, successively testing the URI to identify a core of the URI and any unnecessary elements of the URI. The core of the URI is sufficient to retrieve a version of the content page including all of its signature elements. The method additionally includes, for each URI in the plurality of URI's, updating a set of rules based on the identified core and the identified unnecessary elements. The set of rules establishes a normalized version of the URI.

An apparatus for correcting MAC addresses includes a device port for connecting to a computing device with a colliding MAC address with potential to collide with MAC addresses of other computing devices within a computer network. The apparatus includes a network port for connecting to a network device connected to other computing devices. A reassignment module is configured to assign a non-colliding MAC address in place of the colliding MAC address of the computing device and a replacement module is configured to replace the colliding MAC address of a datagram received on the device port with the non-colliding MAC address and transmit the datagram with the non-colliding MAC address from the network port to the network device, and to replace the non-colliding MAC address of a datagram received on the network port with the colliding MAC address and transmit the datagram with the colliding MAC address to the computing device.

Examples are disclosed and described to facilitate resolution of Internet Protocol address conflicts. An example method includes periodically broadcasting, by the playback device over the network, a probe message, detecting, by the playback device, a change in status associated with the connection, based on the detection, obtaining, by the playback device, a new Internet Protocol (IP) address; and based on the detection, including, by the playback device in at least one probe message broadcast subsequent to the detection, an indication for other playback devices on the network to obtain a new IP address.

A hybrid network communication method is disclosed. A gateway device receives a first association request of a multimode device through a first physical interface, where the first association request includes a MAC address of a second physical interface of the multimode device. The gateway device receives a second association request of the multimode device through a third physical interface, where the second association request includes a MAC address of a fourth physical interface of the multimode device. The gateway device obtains an IPv6 address of the multimode device, and records a first correspondence and a second correspondence. The first correspondence includes the IPv6 address of the multimode device, the MAC address of the second physical interface, and the first physical interface. The second correspondence includes the IPv6 address of the multimode device, the MAC address of the fourth physical interface, and the third physical interface.
