# Close IPs

The IPs used by [Close API](https://developer.close.com/) are not fixed.

We have a stable list, but they (and will) change from time to time when we perform maintenance.

You can see our IP list [here](/v1/docs/which-ip-addresses-need-access-to-my-smtpimap-server).

Since we use AWS, another option is to filter [IP ranges for all AWS](https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html). You would want to filter for EC2 IPs in the "us-west-2" region.
