# IP addresses

We use dynamic IPs, so we do not have a list or range of addresses to share. The best workarounds for most use cases are:

* Check the [user-agent string](https://support.speedcurve.com/docs/private-qa-development-and-staging-websites#user-agent-sniffing) for "PTST/SpeedCurve" to let the SpeedCurve test agents through.
* [Add scripting](https://support.speedcurve.com/docs/synthetic-test-scripts), such as headers or cookies, which you can then filter traffic on.
* Run your own [private test agents](https://support.speedcurve.com/docs/private-agents).

SpeedCurve test agents run in Amazon datacenters, so you could also allow [all traffic](https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html) from Amazon AWS, but we don't recommend doing that.
