# Informational Informational detections are a category within Netography Fusion's Netography Detection Models (NDMs) that provide valuable insights about unusual but not necessarily malicious network behavior. These detections are designed to inform and alert network administrators about irregularities that could impact network functionality or indicate potential vulnerabilities. For example, the 6in4tunnel detection flags IPv6 traffic tunneled over IPv4, which, while not inherently harmful, could be exploited for covert communication. The alltcpflags detection alerts when all TCP flags are set, an unusual condition often associated with network scanning or evasion techniques. While these detections may not always signify an imminent attack, they serve as critical informational tools for maintaining network hygiene and preemptively addressing potential security risks. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.fusion.vectra.ai/detection-models/library/informational.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
