README

Block incoming requests from known bad IP addresses using a centralized JSON feed.

This package fetches a list of bad IPs from a remote API hosted by Mattitja AB and caches them locally. Requests from matching IPs are immediately blocked with a 418 response.

Features

Automatically blocks known malicious IPs
Pulls IP list from a centralized JSON endpoint
Caches data locally to avoid repeated API calls
Designed to run globally across all routes

Installation

composer require mattitjaab/bad-ip-blocker

Usage

Register as global middleware in Laravel 12

Edit bootstrap/app.php:

use Mattitja\BadIpBlocker\Middleware\CheckBadIps;
use Illuminate\Foundation\Configuration\Middleware;

return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        api: __DIR__.'/../routes/api.php',
        ...
    )
    ->withMiddleware(function (Middleware $middleware) {
        $middleware->append(CheckBadIps::class);
    })
    ->create();

This ensures the middleware runs globally on every incoming request.

How it works

On each request, the middleware checks if the client's IP exists in a cached JSON file.
If the cache is missing or older than one hour, it attempts to refresh from https://bad-ip.mattitja.cloud/api/json.
If the IP is found in the list, the request is blocked with a 418 response.

Cached file location

Cached data is stored at:

storage/app/private/bad_ips.json

Delete this file to force a refresh.

Example response when blocked

HTTP/1.1 418 Blocked
Content-Type: text/plain

Blocked.
