php - 我如何通过php spamhaus ip黑名单查询

Question

正在尝试查询 spamhaus.org 以获取列入黑名单的 ip。一个例子是 69.35.160.59如果我转到 https://www.spamhaus.org/lookup/ 并输入它，它会显示在与 112.198.83.17 相同的黑名单中，但是以下代码返回一个空数组。

我打印出 url，它在反向 ip 中看起来格式正确17.83.198.112.zen.spamhaus.org。

有什么想法吗？

<?php

    $ip = "112.198.83.17";
    $blacklist = "zen.spamhaus.org";
    $url = implode(".", array_reverse(explode(".", $ip))) . ".". $blacklist;
    echo "$url<br>";
    $record = dns_get_record($url);
    print_r ($record);

?>
