How to:Block adult content on smartphone/zh

色情是印刷品或视觉材料，其中包含对生殖器或性活动的明确描述或演示；这些材料旨在刺激色情，而不是审美感觉或情感。

问题在于色情在互联网上无处不在，因此很难完全避免色情。但是，大多数父母想知道他们可以采取哪些措施来防止孩子在使用数字设备时看到成人内容。

安全的Google搜索

将Google设置为默认搜索引擎。

检查孩子使用的所有浏览器（Chrome，Safari，Internet Explorer，Firefox等），并确保将Google用作默认浏览器。在iPhone上，转到手机的设置，向下滚动并单击Safari，然后在“搜索引擎”部分中选择Google。

开启安全搜索

在移动设备上，打开Goog​​le应用（如有必要，请下载）。点击齿轮图标，向下滚动并单击“搜索设置”按钮，然后在“安全搜索过滤器”部分中单击“过滤器显式结果”。在台式机和笔记本电脑上，访问www.google.com并单击右下角的“设置”按钮；单击“搜索设置”，然后单击“打开安全搜索”，然后单击“锁定安全搜索”。

定期检查所有设备

对孩子使用的所有设备执行第一和第二步。定期检查您的Google应用和设置部分，以确保未禁用安全搜索。

重要说明

免费使用Google SafeSearch，但并非没有错误。安全搜索仅过滤搜索结果-如果直接在浏览器中输入URL，则不会阻止访问色情网站。

使用安全的DNS服务阻止成人内容

域名系统（DNS）的工作方式

可以将DNS与Internet上的数字电话簿进行比较。人们通过在浏览器的地址栏中输入网站域名来访问网站，例如“ example.com”（也称为“主机名”），而计算机使用IP地址（许多数字）进行通信，例如127.0.0.1。 DNS将域名转换为IP地址，以便您的计算机可以转到该地址并请求信息。 DNS服务器遍布世界各地，并拥有公共IP地址和与其关联的主机名的数据库。

How DNS Blocking Works

From this information, it is clear that you can use DNS servers to categorize and filter IP addresses to restrict access to certain categories of sites. It means that if you instruct a device to use a specific DNS server, the database of which does not contain addresses of certain sites, it will be impossible to access these sites from that particular device.

How to block access to pornographic content using DNS

Any device uses DNS to connect to the Internet. Names of the settings responsible for DNS may differ, depending on the device, version of the operating system, language, etc. Therefore, you may not find on your device items that exactly match the example below. However, don't be upset: all you need to do is open the device's Settings and look for Network Settings or Wi-Fi Settings, which should contain items that allow you to change DNS servers (also called NameServers) to the IP address, provided by the secure DNS service.

Let's look at an example, where the free CleanBrowsing service is used:

For Mac and Linux computers: go to Settings-> Network-> Wi-fi-> Advanced and change the DNS servers to IP address 185.228.168.168

For ChromeBook: go to Settings-> Network-> Wifi and configure custom NameServers, stating the following IP addresses there: 185.228.168.168 and 185.228.169.168

For Windows 10: click Start -> Settings -> Network & Internet -> Ethernet or Wi-Fi (depending on your connection) -> select the network connection-> under the "IP settings" section, click the Edit button, from the drop-down menu select Manual option, turn on the IPv4 toggle switch and type 185.228.168.168 and 185.228.169.168 into the "Preferred DNS" and "Alternate DNS" fields.

For iPhone, Android, and iPad: go to Settings -> Wi-Fi Settings and configure Name Server by specifying the IP address 185.228.168.168 in it.

For your home router and complete home protection: Log in to your router, find "Settings" or "DNS Settings" and change the Nameserver, specifying the IP address 185.228.168.168 in it.

If possible, configure DNS on your home router, so that all devices in your home will be protected. This applies to Internet-connected TVs, game consoles (xBox, Playstation, Nintendo Wii), computers or mobile devices.

Make sure your device is compatible with Family Link. (https://families.google.com/familylink/device-compatibility/).

Do download the Family Link app to your Android device from Google Play Store. Do the same on the Android device, from which you want to control your child's device. Next, follow the instructions to configure the application on both devices. After that, you can change your child's Android device settings remotely.

Attention! The Google Family Link application itself does not block anything, but it allows you to control the child's device from your device. For example, you can set up a secure Google search, blocking unwanted content via DNS or using specialized software with parental controls.

Use special applications for parental control
