Abstract: A computer network node discovery process provides for collecting discovery data at least in part by having a computer query computer network nodes. The discovery data can include IPv6 addresses or MAC addresses or both. The discovery data can be expanded by converting IPv6 addresses to MAC addresses or converting MAC addresses to IPv6 addresses. The resulting expanded discovery data can be used to update a network inventor database at least in part by entering IPv6 or MAC addresses resulting from the conversions.

Abstract: Remaining trust levels (RTLs) are computed for respective computer-inventory data sets. The computations involve applying decay formulae to initially assigned trust levels (ATLs). The data sets can then be consolidated so as to reconcile apparently inconsistent data by comparing respective RTLs.
