# IP whitelist
|
|
|
|
|
|
|
|
|
|
> Introduced in GitLab 9.4.

|
|
NOTE: **Note:**
|
|
|
|
|
We intend to [rename IP whitelist as `IP allowlist`](https://gitlab.com/gitlab-org/gitlab/-/issues/7554).
|
|
|
|
|
|
|
|
|
|
GitLab provides some [monitoring endpoints](../../user/admin_area/monitoring/health_check.md)
|
|
|
|
|
that provide health check information when probed.

|
|
|
|
|
|
|
|
To control access to those endpoints via IP whitelisting, you can add single
|
|
|
|
|
hosts or use IP ranges:
