ip-restriction

Description

The ip-restriction can restrict access to a Service or a Route by either whitelisting or blacklisting IP addresses. Single IPs, multiple IPs or ranges in CIDR notation like 10.10.10.0/24 can be used.

Attributes

Name	Type	Requirement	Default	Valid	Description
whitelist	array[string]	optional			List of IPs or CIDR ranges to whitelist.
blacklist	array[string]	optional			List of IPs or CIDR ranges to blacklist.
message	string	optional	Your IP address is not allowed.	[1, 1024]	Message returned in case IP access is not allowed.

One of whitelist or blacklist must be specified, and they can not work together. The message can be user-defined.

How To Enable

Creates a route or service object, and enable plugin ip-restriction.

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "plugins": {
        "ip-restriction": {
            "whitelist": [
                "127.0.0.1",
                "113.74.26.106/24"
            ]
        }
    }
}'

Default returns {"message":"Your IP address is not allowed"} when unallowed IP access. If you want to use a custom message, you can configure it in the plugin section.

"plugins": {
    "ip-restriction": {
        "whitelist": [
            "127.0.0.1",
            "113.74.26.106/24"
        ],
        "message": "Do you want to do something bad?"
    }
}
