Test private websites and APIs
Allowlist BrowserStack load generator IPs to run load tests against private or internal websites and APIs.
If your website or API is hosted behind a firewall and is not exposed to the public internet, your network blocks incoming traffic from BrowserStack by default. To run load tests against these private or internal environments, allowlist the BrowserStack load generator IP addresses in your firewall, security group, or proxy settings.
Each load zone uses a fixed set of outbound IP addresses. Allowlist the IP addresses for every load zone you select when you configure your test.
Allowlist the IP addresses only for the load zones you select for your test. If you change the selected load zones later, update your firewall rules to match.
IP addresses by load zone
After you allowlist these IP addresses, the load generators in the selected zones can reach your private website or API, and you can run your load tests as usual.
| Region | IP address |
|---|---|
| US East (Virginia) | 54.210.41.31 |
| US East (Virginia) | 98.90.250.103 |
| US West (North California) | 52.8.159.15 |
| Asia Pacific (Mumbai) | 13.200.98.20 |
| EU West (London) | 35.177.222.200 |
| EU Central (Frankfurt) | 18.194.133.75 |
