# Create or replace an origin cloud region mapping
PUT/zones/{zone\_id}/origin/cloud\_regions/{origin\_ip}
Creates a new IP-to-cloud-region mapping or replaces the existing mapping for the specified IP. PUT is idempotent — calling it repeatedly with the same body produces the same result. The IP path parameter is normalized to canonical form (RFC 5952 for IPv6) before storage. The vendor and region are validated against the list from `GET /zones/{zone_id}/origin/cloud_regions/supported_regions`. Returns 400 if the `origin_ip` in the body does not match the URL path parameter. Returns 403 (code 1164) when the zone has reached the limit of 3,500 IP mappings.
##### Security
API Token
The preferred authorization scheme for interacting with the Cloudflare API. Create a token.
**Example:**Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY
API Email + API Key
The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key.
**Example:**X-Auth-Email: user@example.com
The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys.
**Example:**X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194

##### Body ParametersJSONExpand Collapse
origin\_ip: string
Origin IP address (IPv4 or IPv6). For the single PUT endpoint (`PUT /origin/cloud_regions/{origin_ip}`), this field must match the path parameter or the request will be rejected with a 400 error. For the batch PUT endpoint, this field identifies which mapping to upsert.

region: string
Cloud vendor region identifier. Must be a valid region for the specified vendor as returned by the supported\_regions endpoint.
