Release IP range GitLab integration

Good afternoon,
I am only wanting to release the ip range from gitlab integration to access my infrastructure to run the webhook script.
Does anyone know what range gitlab uses?
Thank you.

GitLab.com is using the IP range 34.74.90.64/28 for traffic from its Web/API fleet. This whole range is solely allocated to GitLab. You can expect connections from webhooks or repository mirroring to come from those IPs and whitelist them.
