What IP Addresses are used by Load Impact's to generate load?
This article contains the information regarding the various IP addresses Load Impact will use during a test, validation or script creation.
If you are looking to run tests behind a firewall completely, you may want to consider our new open source load generator, k6. k6 allows you to run tests locally and stream those results into Load Impact Insights, for analysis. To get started with k6, please refer to our Quick Start Guide
If you are unable to whitelist a large ranges of IPs, you may want to consider another method, such as header or query parameter whitelisting, as described in this article
The main loadimpact.com IP address:
126.96.36.199 - Ashburn
This used for validations, and must be included in every test, regardless of loadzone. Please refer to the Load Zone section of this document for the full range of IP addresses used when testing.
Auto-generated load scripts/Page Analyzer IP address:
This is only for URL generated tests from within the Load Impact platform.
Proxy Recorder IP addresses:
The Session Recorder IP address is not fixed. It does not change often, but it is a good practice to re-resolve the hostname and make necessary changes to the firewall if this is fixed to the IP address. We highly recomend adding the hostname proxy.loadimpact.com instead of the IP address if possible. IP address for Session Recorder (Updated on 11/09/2014): 188.8.131.52
Note: Please ensure that your servers are allowed outbound connections within the port range 20000 - 21000 as well.
Load Impact uses AWS for cloud load generators. For the IP addresses used in the different load zones and filtering methods please refer directly to Amazon.
If you prefer to view the ranges directly, within the above link, the ip-ranges.json file provides the updated list of IP addresses used by our load generators. In order to know which IP range/s can be used, you need to filter the
service of type EC2 and the
region of the selected load zone/s in your test configuration.
The zone codes are mapped as follows:
|us-east-1||US East (Ashburn)|
|us-east-2||US East (Columbus)|
|us-west-1||US West (Palo Alto)|
|us-west-2||US West (Portland)|
|ap-northeast-1||Asia Pacific (Tokyo)|
|ap-northeast-2||Asia Pacific (Seoul)|
|ap-southeast-1||Asia Pacific (Singapore)|
|ap-southeast-2||Asia Pacific (Sydney)|
|ap-south-1||Asia Pacific (Mumbai)|
|sa-east-1||South America (São Paulo)|
