Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.snyk.io/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/start-scanning/overview-scan-access-and-connectivity/scanner-ip-address.md). # Scanner IP address Snyk API & Web uses the following IP addresses to make requests. ## Target scans Customers hosted in US infrastructure: * **18.235.241.170** (AWS IP) Customers hosted in AU/APJ infrastructure: * **52.65.214.19** (AWS IP) * **13.237.213.25** (AWS IP) All other customers: * **52.19.40.38** (AWS IP) ## Asset discovery Customers hosted in US infrastructure: * **44.205.45.120** (AWS IP) Customers hosted in AU/APJ infrastructure: * **3.104.172.219** (AWS IP) * **13.211.189.220** (AWS IP) All other customers: * **52.16.191.244** (AWS IP) If you are unsure where your account is hosted, check all IP addresses or contact the support team for assistance. If you have your own single tenant or dedicated infrastructure, contact the support team. ## Deprecated IP addresses The following IP addresses are deprecated. No traffic originates from them: * 35.190.194.212 (GCP IP) * 35.187.52.245 (GCP IP) ## Related information You can also identify Snyk requests through the user-agent header. For more information, visit [Identify scanner requests](/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/start-scanning/overview-scan-access-and-connectivity/identify-scanner-requests.md). If you use a Web Application Firewall (WAF) in front of your target, it can block scan requests from Snyk IP addresses and cause the scan to fail. To avoid that, visit [Configure IPs in WAFs](/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/start-scanning/overview-scan-access-and-connectivity/configure-ips-in-wafs.md). --- # 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.snyk.io/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/start-scanning/overview-scan-access-and-connectivity/scanner-ip-address.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.
