Node Detection in Mixed IPv4 IPv6 Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing node detection methods in networks, particularly those involving mixed IPv4 and IPv6 environments, face challenges in efficiently identifying and confirming the operational status of communication equipment across a large scale, leading to increased network loads and slower detection processes.
Innovation Solution
A node detection apparatus and method that acquires address information from a DNS server, confirms the operational status of communication equipment using ICMP requests, and registers active nodes, incorporating both IPv4 and IPv6 protocols to expedite the detection process and reduce network load by setting address ranges and excluding already registered nodes.

Engineering Contradiction Analysis
1Productivity
If traditional node detection methods are used in mixed IPv4 and IPv6 networks, then node detection can be performed, but network load increases and detection speed decreases
Solution Approach 1:
The system performs preliminary actions by acquiring address information from DNS server in advance and maintaining a registration database of known nodes. Before performing full node detection, the system first checks against already registered nodes, avoiding redundant detection operations and reducing network load while maintaining detection effectiveness
Solution Approach 2:
The detection process is segmented into distinct phases: first acquiring address information from DNS server, then performing operation confirmation only on newly discovered addresses, and finally registering confirmed nodes. This segmentation allows the system to handle large-scale networks efficiently by breaking down the detection task into manageable steps rather than performing exhaustive detection on all nodes simultaneously
2Reliability
If comprehensive node detection is performed across large scale networks, then all nodes can be identified, but the detection process becomes slower
Solution Approach 1:
The system implements feedback mechanisms by continuously updating the node registration database with confirmed operating nodes. Subsequent detection operations use this database to avoid re-detecting already registered nodes, creating a feedback loop that improves detection efficiency over time while maintaining complete node identification across the network
Solution Approach 2:
By acquiring address information from DNS server beforehand and maintaining an updated registry of known nodes, the system performs preliminary work that eliminates the need for repeated comprehensive scans. This preliminary action ensures reliable node identification while significantly reducing detection time in large-scale networks

AI summary
There is provided a node detection apparatus including: an acquisition section that acquires address information of communication equipment managed by a DNS server; an operation confirmation section that confirms operations of the communication equipment based on the address information acquired by the acquisition section; and a node registration section that registers the communication equipment having the address information acquired by the acquisition section as an operating node, based on a result of the operation confirmation by the operation confirmation section.
