A whitelist provides access to specified IP addresses and programs when your Security policy would otherwise prevent that access. If your server policy allows all outbound http/https communication to any IP address or website, you do not need to make any changes. However, if your server policy denies access to most or all external IP addresses and websites, you must configure a whitelist to enable some features to work.
For domain, port, and troubleshooting information, see Implementation Details below.
|Okta IP Addresses
To ensure proper connectivity to Okta for all Okta agents and end users, add Okta system IP addresses to your whitelist based on this list, which is managed and updated by AWS:
IP addresses in this list are grouped by the following:
We recommend viewing this file with an online JSON viewer of your choice. The Okta Whitelist IP ranges can also be obtained by super admins who need to maintain the IP whitelist.
Note: Okta whitelisted IP addresses may need to be added to your inbound firewall rules for Okta to communicate successfully with any installed agents that are located on your internal network.
The following information helps you configure whitelisting for your orgs.
The Okta service uses SSL/TLS for all communication. If your policy requires a port number, port 443 must be whitelisted for the IP addresses provided in this document, unless otherwise noted.
Required Okta Domains
If your company whitelists domains, add the following domains to your list of allowed domains:
For most firewall or proxy systems, we recommend that you specify a whitelist of DNS addresses for Okta services so that outbound connections can be made. For a list of current IP ranges for the content delivery network (CDN), refer to 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 whitelisted under port 80:
Third Party Services
Okta Mobile may require whitelisting of the following third party domains for outbound connections to these services:
