Example methods are provided for a network scanning controller to perform agent-based network scanning in a software-defined networking (SDN) environment. In one example, the method may comprise identifying multiple networks for which network scanning is required, performing a first network scan using a first agent to obtain first address mapping information associated with multiple first workloads, and performing a second network scan using a second agent to obtain second address mapping information associated with multiple second workloads. The first agent and the multiple first workloads may be located in a first network, and the second agent and the multiple second workloads in a second network. The method may also comprise generating aggregated address information based on the first address mapping information and the second address mapping information.

An IoT service of a provider network may be used to increase the edge device address space while complying with a radio communication protocol. This may allow a service provider to manage a much larger number of client devices that use a particular radio communication protocol that specifies a limited address space (e.g., LoRaWAN). When the IoT service receives a join request via a private gateway of the client network, the service determines, based on the private gateway ID, the client ID of the client that owns the private gateway/client network. The service may generate a unique internal ID for the edge device by combining the client ID with an assigned device ID. The internal ID identifies the edge device as an activated device of the edge network.

A first computer is connected to a communication network and is assigned a first network address on the communication network. A second computer is connected to the communication network and is assigned the first network address on the communication network. A first message, including the first network address and a request to generate a random number, is transmitted by the first computer via the communication network. A first reply message, including the random number, is received from the second computer in response to the request. A second network address is assigned for the second computer by the first computer based on the random number. A second message, including the second network address and the random number, is transmitted by the first computer via the communication network.

A server and an updating method for a MAC address are provided in the present application. The server includes: a network chipset having a preset first MAC address; a first non-volatile memory storing the first MAC address of the network chipset; a second non-volatile memory storing a first BIOS code data; a central processing unit coupled to the network chipset and the second non-volatile memory; and a baseboard management controller coupled to the central processing unit, the first non-volatile memory, and the second non-volatile memory. The baseboard management controller reads the first non-volatile memory to obtain the first MAC address and stores a second BIOS code data including the first MAC address to the second non-volatile memory, causing the first BIOS code data to be overwritten by the second BIOS code data

Some embodiments provide a method for a network controller that manages multiple logical networks implemented by multiple managed forwarding elements (MFEs) operating on multiple host machines. The method receives a notification from a particular MFE that an interface corresponding to a logical port of a logical forwarding element has connected to the particular MFE and has a particular logical network address. The method assigns a unique physical network address to the interface. Each of multiple interfaces connected to the particular MFE is assigned a different physical network address. The method provides the assigned unique physical network address to the particular MFE for the particular MFE to convert data messages sent from the particular logical network address to have the unique physical network address.
