All our servers are currently hosted on Amazon AWS eu-west-1 in Ireland. Below is a list of the IPs Hotjar uses to send egress, outgoing, traffic from which you can whitelist if required on your end.
126.96.36.199 188.8.131.52 184.108.40.206
The IPs listed above do not cover the actual domain
The actual domain is https://insights.hotjar.com. This is due to it being served by our CDN provider. We suggest whitelisting the domains *.hotjar.com especially for applying CSS to Heatmaps. This is not needed for CSS in Recordings.
It may be required for you to whitelist our browser userAgents as well. If that is the case, head to How do Hotjar Heatmaps work?: A Technical Explanation for the full list of our browser userAgents.
The IPs listed above do not cover the IPs whitelisting for Forms
If you are needing to whitelist our IPs for Forms, reach out to our Support team for further instructions.
