    • Mechanisms are provided for automatic address range detection for an IP network. Flow data is obtained comprising the source or destination IP addresses for the flow and one of: the other of the source or destination IP addresses; or direction data identifying the flow direction across the network boundary. A tree is generated representing IP addresses in the flow data. IP addresses with initial portions in common are represented in the tree with a node in common. Weights are assigned to nodes in the tree based on occurrences of the represented IP addresses in the flow data. The IP address range of the network is detected by identifying, based on the assigned weights, the node associated with the last initial address portion common to all IP addresses in the network. A device is automatically configured with the IP address range to differentiate IP addresses inside and outside the network.
    • 为IP网络的自动地址范围检测提供了机制。 获得流数据,其包括用于流的源或目的地IP地址和以下之一:源或目的地IP地址中的另一个; 或方向数据标识跨越网络边界的流向。 生成表示流数据中的IP地址的树。 具有共同的初始部分的IP地址在树中被表示为具有共同的节点。 基于流数据中所表示的IP地址的出现,权重被分配给树中的节点。 通过基于分配的权重,识别与网络中所有IP地址共同的最后初始地址部分相关联的节点来检测网络的IP地址范围。 设备自动配置IP地址范围,以区分网络内外的IP地址。
