Allowed IP addresses are available with GitHub Enterprise Cloud. For more information, see "GitHub's products."

Organization owners can manage allowed IP addresses for an organization.

About allowed IP addresses

You can restrict access to organization assets by configuring an allow list for specific IP addresses. For example, you can allow access from only the IP address of your office network. The allow list for IP addresses will block access via the web, API, and Git from any IP addresses that are not on the allow list.

You can approve access for a single IP address, or a range of addresses, using CIDR notation. For more information, see "CIDR notation" on Wikipedia.

To enforce the IP allow list, you must first add IP addresses to the list, then enable the IP allow list. You must add your current IP address, or a matching range, before you enable the IP allow list.

You can also configure allowed IP addresses for the organizations in an enterprise account. For more information, see "Enforcing security settings in your enterprise account."

Using GitHub Actions with an IP allow list

Warning: If you use an IP allow list and would also like to use GitHub Actions, you must use self-hosted runners. For more information, see "Hosting your own runners."

To allow your self-hosted runners to communicate with GitHub, add the IP address or IP address range of your self-hosted runners to the IP allow list. For more information, see "Adding an allowed IP address."
