At Ahrefs, we operate two primary web crawlers—AhrefsBot and AhrefsSiteAudit—to support our suite of tools and services. We crawl from publicly published IP ranges. Please whitelist all of our IP ranges to make your website accessible to our bots.

We take responsibility for the requests coming from our publicly published IPs. In case you encounter any issues with our IP ranges, please email to our support.

You can pull all of our IP addresses in JSON format as individual IPs or IP ranges. Or copy them as text from the below section.
