Patent number: 11962568Abstract: The disclosed technology is directed towards locating and counting unused nodes, such as free Internet Protocol version 4 (IPv4) address blocks. A hierarchical structure of nodes is created from an origin block to a specified lower level, and the hierarchical structure is processed using mapping and eliminating to locate free nodes. A first node group comprises node(s) in use, a second node group identifies intermediate subnets between the first node of the first node group and the specified origin block, and a third node group identifies any subnets hierarchically below node(s) in use. Unused (free) node count information is obtained based on nodes below the origin block that are not in the first node group, the second node group, or the third node group.Type: GrantFiled: April 6, 2023Date of Patent: April 16, 2024Assignee: AT&T Intellectual Property I, L.P.Inventors: Xiaowen Mang, Anestis Karasaridis

Publication number: 20230254207Abstract: Aspects of the subject disclosure may include, for example, determining, an application requirement for a server of a data center geographically separated from a central location. A configuration file adapted for the server according to the application requirement is obtained at the central location and a host processor located at the data center is selected according to the application requirement. A static IP address preassigned to an administrative portion of the selected host processor is identified. The selected host processor is initialized remotely over a wide area network via the administrative port without utilizing any software resources pre-existing at the data center. The initializing configures the selected host processor according to the configuration file to service the application requirement. Other embodiments are disclosed.Type: ApplicationFiled: April 18, 2023Publication date: August 10, 2023Applicant: AT&T Intellectual Property I, L.P.Inventors: Srinandan Hullahalli, Sunil Maloo, Anestis Karasaridis, Robert Roschewsk

Publication number: 20220321525Abstract: The disclosed technology is directed towards locating Internet Protocol version 4 (IPv4) address blocks that are not supernets to subnet address blocks. A list of IPv4 address blocks is first processed to determine supernet/subnet relationships across octets, to remove the supernets and provide a reduced list. The reduced list is iteratively processed in descending prefix length order to identify candidate supernets at each prefix length, determine which of the candidate supernets are actual supernets, remove the actual supernets, and move the remaining candidates to a leaf list. At the end of the iterations, the leaf list contains the IPv4 address blocks that do not have subnets (are not supernets).Type: ApplicationFiled: April 5, 2021Publication date: October 6, 2022Inventors: Xiaowen Mang, Anestis Karasaridis
