Crisp uses a large outbound and inbound IP space. Some corporate offices or government agencies need to whitelist IP addresses their employees should be allowed to use. Here's a list that will help them whitelist Crisp (this only affects the operators using Crisp apps, not your actual website visitors).

We try to keep this list up-to-date on a best-effort basis. Our infrastructure changes a lot in time, so more IPs might be added in the future.

The location of the datacenter serving each IP is indicated with a country flag. Crisp tries to route users to the datacenter that's near them to reduce latency. When the US flag is indicated, the IP is usually anycast, which means there are multiple distributed datacenter serving it (via Cloudflare).

Inbound IPs

HTTP service IPs
