This article aims to provide insights on how APIs can block specific IPs in Okta.

• Okta API
• Network Zones 
• Blocklist

The Okta Zones API can be used to configure a Network Zone inside the Okta tenant, blocking specific IPs or IP ranges.

To create a Network Zone, the following API call can be used: 

{yourOktaDomain}/api/v1/zones

NOTE:

• For an IP Network Zone, ensure to define either gateways or proxies.
• For a Dynamic Network Zone, ensure to define at least one of the following: asns, locations, or proxyType.
• For an Enhanced Dynamic Network Zone, ensure to define at least one of the following: asns, locations, or ipServiceCategories.
• This operation can also be done from the Okta Admin Console by going to Security > Networks.
