Allow access to Okta IP addresses

An IP allow list is used to provide access to selected IP addresses and programs that your network server policy could typically block.

  • If your server policy allows all outbound HTTP and HTTPS communication to any IP address or website, you do not need to make any changes.
  • If your server policy denies access to most or all external IP addresses and websites, you must configure an allow list to enable some features to work.

For domain, port, and troubleshooting information, see Implementation details.

Okta IP addresses

For proper connectivity to Okta for all Okta agents and end users, add Okta system IP addresses to your allow list based on this AWS-managed list:

This list includes all existing IP addresses and any new IP addresses reserved for future updates.

If your organization configures an allow list for domain names, be sure to add awsglobalaccelerator.com to that domain name allow list. This domain name is in addition to any existing domain names you have already configured.

IP addresses in this list are grouped by the following:

  • Production (us_cell_1 - us_cell_7, us_cell_10 - us_cell_12, us_cell_14)
  • Production EMEA (emea_cell_1)
  • Production EMEA (emea_cell_2)
  • Production HIPAA (us_cell_5,us_cell_10)
  • Production APAC (apac_cell_1, apac_cell_2)
  • Preview (preview_cell_1 - preview_cell_3)
  • Preview EMEA (preview_cell_2)

We recommend viewing this file with an online JSON viewer of your choice. The Okta IP range allow list can also be obtained by super admins who need to maintain the IP allow list.

To learn more about IP address ranges that can be allow-listed for CDN, refer to this article from Amazon Web Services.

You might need to add Okta allow-listed IP addresses to your inbound firewall rules so that Okta can communicate with any agents that are installed on your internal network.

Implementation details

Review the information in this section to learn how to configure and implement allow listing for your org.

Ports The Okta service uses SSL/TLS for all communication. If your policy requires a port number, port 443 must be allow listed for the IP addresses provided in this document, unless otherwise noted.

  • *.okta.com
  • *.mtls.okta.com

Content Delivery Network (CDN) Okta static UI assets (JavaScript, CSS and images) can be delivered to browsers through an international CDN for faster downloading of assets to customers outside of the USA.

For most firewall or proxy systems, Okta recommends specifying an allow list of DNS addresses for Okta services so that outbound connections can be made. To learn more about IP address ranges that can be allow-listed for CDN, refer to this article from Amazon Web Services.
Certificate revocation troubleshooting Various problems can arise when attempting to revoke a certificate. For example, some clients will fail to connect to SSL/TLS endpoints when they are unable to reach a revocation server. If you experience trouble with certificate revocation, ensure that you have the following domain names allow listed under port 80:
  • ocsp.digicert.com
  • crl3.digicert.com
  • crl4.digicert.com
Third-party services Okta Mobile may require allow listing of the following third party domains for outbound connections to these services:
  • *.mapbox.com
