To ensure that employee IP ranges are excluded from all Statsig events and A/B tests, you can utilize holdouts. Holdouts are a feature that allows you to compare a group of users who are not exposed to any experiments against the broader population that is.
By creating a targeting gate with a regex that encapsulates the IP addresses of your employees, you can then use this targeting gate to establish a holdout. Setting this holdout to global will effectively exclude the specified IP ranges from any experiments, gates, or other features.
Additionally, if you maintain a list of user IDs for your employees, you can create a segment using these IDs instead of relying on IP addresses. This segment can then be referenced in the holdout to achieve the same exclusion effect.
It is important to note that holdouts are subject to analysis, which may lead to additional billing due to the insights they provide on the overall impact of experimentation efforts.
