Its core features and advantages can be summarized as follows: * **High-Purity IP Sources**: Uses residential IP ranges assigned by real ISPs, with minimal prior usage history and higher reputation scores * **High Connection Stability**: Backed by data-center-grade network architecture, offering low latency, high bandwidth, and high availability * **Lower Ban Risk**: Less likely to be identified or trigger risk-control mechanisms by target websites compared to standard proxies * **Long Session Support**: Supports fixed IPs or extended session retention, ideal for account-based business use cases * **Broad Compatibility**: Suited for cross-border e-commerce, ad verification, SEO monitoring, data collection, social media operations, and more * **Balance of Performance and Trustworthiness**: Maintains a high access success rate while balancing network performance and cost-efficiency ## **Need Help?** If you need further clarification or assistance with location targeting, feel free to reach out to us via: * Email: **** * Live Chat:[ **9HTTP**](https://www.9http.com/) offers 24/7 support on our website --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://doc.9http.com/en/proxies/premium-isp-proxies/getting-started.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
