For exclusive use of IP addresses that are employed by Prerender, please refer to the list provided on this link: https://ipranges.prerender.io/ipranges-all.txt. It is important to note that the list is dynamic, so it is highly recommended that you update it on your end regularly, say, once per month.

The above-mentioned addresses are our egress IP addresses used by the rendering cluster, and our ingress IP and Sitemap crawler might use different IP addresses. Specifically, our Sitemap crawler employs a dynamic IP address. For this reason, it is recommended that you permit the Sitemap crawler's connection based on the following user-agent string:
Prerender (+https://github.com/prerender/prerender)

We have a mix of servers in the US and Europe. Paid customers can request rendering from our US cluster only if you don't want to permit IPv6 subnets from your side.

From July 1, 2024, we’ll be using RFC6555 Happy Eyeballs so if you have reachable IPv6 addresses, those will be used.
