Address filter element. Optional in <rule> elements. Overrides attribute::ClientAddressFilter when the rule is applied.
Comma-separated list of IP addresses. Each individual address may include an optional netmask suffix to allow specification of IP address ranges. See [attribute::ClientAddressFilter](../../../../../ir-api/material-cat/image-rendering-api-ref/c-ir-material-catalog/c-ir-attributes-reference/r-ir-clientaddressfilter.md#reference-52a541cec0b0424faf263d1fb4946b5f) for details.
Access to this image catalog can be restricted to one or more specific IP addresses by specifying them in an <addressfilter> element. A "request refused" error is returned to the client if the client IP address is not matched.
Access is not restricted if <addressfilter> is empty or not specified.
If the <expression> in the <rule> element is absent or empty, the <addressfilter> is applied to all requests.
localhost is always implicitly part of the ClientAddressFilter definition, even if not explicitly specified. Requests originating from localhost are never rejected, regardless of the ClientAddressFilter specification.
