IP Address / Range

IP authentication restricts an endpoint to callers from defined IP addresses or CIDR blocks.

You can configure:

• A single IP address (for example 192.168.1.152)
• A CIDR block (for example 192.168.1.0/24)

You can provide multiple entries. If the request includes several addresses (for example via X-Forwarded-For), every address in the request must match an allowed entry.

Values support variables using the same mapping syntax as other authentication fields.
