> For the complete documentation index, see [llms.txt](https://docs.transparentedge.eu/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.transparentedge.eu/config/network-access-control-list/auto-generated-lists.md). # Auto generated lists Some services will automatically create network ACLs, these lists will have specific functions which we will explain below. ## Auto AntiDDoS list The AntiDDoS system will generate a list of suspicious IPs and add them to a Network ACL named "**ddos\_identified\_ips**". This list serves an informational purpose only and does not take any further action against the IPs. You can utilize this list as needed. ## **Block this IP button** In the [Analytics](/getting-started/dashboard/estadisticas.md) section, you will find a button "**Block this IP**" under the "IP address table". The blocked IPs will be added to a Network ACL named "**auto\_blacklist**". Also a [deny VCL configuration](/getting-started/dashboard/auto-provisioning/network-acls.md#deny-list-example) will be created for the IPs in this list. IPs on this list will be unconditionally blocked unless a TTL is set when blocking the IPs. ## Auto Block IPs anomaly reaction The "[Block IP](/security/anomaly-detection/automatic-reactions.md#reactions-types)" reaction in [Anomaly Detection service](/security/anomaly-detection.md), automatically blocks an IP if its requests per second exceed the predefined threshold. These IPs are then added to the "**auto\_blacklist**" ACL. By default, blocked IPs have a TTL of 1 hour, though this can be adjusted when setting the threshold. ## Captcha reaction The "[Captcha](/security/anomaly-detection/automatic-reactions.md#reactions-types)" reaction in [Anomaly Detection service](/security/anomaly-detection.md), automatically adds an IP to the "**auto\_captcha**" ACL if its requests per second exceed the predefined threshold. These IPs are then required to solve a Captcha puzzle for each request. By default, Captcha have a TTL of 1 hour, though this can be adjusted when setting the threshold. ## JS Challenge reaction The "[JS Challenge](/security/anomaly-detection/automatic-reactions.md#reactions-types)" reaction in [Anomaly Detection service](/security/anomaly-detection.md), automatically adds an IP to the "**auto\_jschallenge**" ACL if its requests per second exceed the predefined threshold. These IPs are then required to pass a JS Challenge for each request. By default, JS Challenge have a TTL of 1 hour, though this can be adjusted when setting the threshold. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.transparentedge.eu/config/network-access-control-list/auto-generated-lists.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
