laravel how to properly esacpe inet_aton insertion?

Question

so for example to save user ip into db:

$ip = Request::getClientIp();
...
$post->user_ip = DB::raw("inet_aton('$ip')");
$post->save()

I don't really like this code how to properly escape the $ip variable?

Edit: I am looking for a way of binding the variable instead of directly using him like:

DB::insert('insert into users (ip) values (?)', [$ip]);

to protect from sql injection

From Laravel docs :

You may also access the raw, underlying PDO instance using the getPdo method on a connection instance:

 $pdo = DB::connection()->getPdo(); 

So, in your case:

$ip = Request::getClientIp();
$ip = DB::connection()->getPdo()->quote($ip); // the escaping part

$post->user_ip = DB::raw("inet_aton($ip)");
$post->save();
