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.

Inbound IPs

Our inbound IP addresses are no longer shared. As they are all dynamic and may thus change over time without notice, we have chosen not to share them.

Outbound IPs

SMTP / Email service IPs

Those services are used to deliver emails to you and your users, from Crisp.
