The method of changing DNS varies from device to device, but the overall operation is not difficult. 1. Windows system: Enter the current network properties through "Control Panel" → "Network and Sharing Center", and select Manually enter the DNS address in IPv4 settings. 2. Mac system: Select the current connection in "System Settings" → "Network", click "Advanced" to switch to the "DNS" tab page, and add custom DNS. 3. Router settings: Log in to the background management interface (such as 192.168.1.1), find the DNS configuration items and fill in manually. 4. Mobile phone settings: Android needs to enter Wi-Fi settings and switch to static IP mode. iPhone needs to scroll to the bottom and click "Configure DNS" and set it to manual mode. The operating core of all devices is to find the network settings and specify the DNS address to complete the modification.

Changing DNS is actually not difficult. The key is to know which system you are using and then find the corresponding setting location. Most people use DNS assigned by the operator by default, but sometimes they want to improve network speed, bypass certain restrictions, or enhance privacy, and manually changing DNS will come in handy.

1. How to change DNS on Windows system

Modifying DNS on Windows is one of the most common operations and is suitable for most home users.

• Open Control Panel → Network and Internet → Network and Sharing Center
• Click on the currently connected network (such as "Ethernet" or "WLAN")
• Click "Properties" → Double-click "Internet Protocol Version 4 (TCP/IPv4)"
• Select "Use the DNS server address below" in the pop-up window
• Fill in the preferred DNS and alternate DNS, such as Google's 8.8.8.8 and 8.8.4.4

Note: If you are using IPv6, you can also modify it in the IPv6 settings, but the current mainstream is still IPv4.

2. How to set up custom DNS on Mac

The operating logic of Apple computers is different from that of Windows, but it is not complicated.

• Open System Settings → Network
• Select the currently used network connection (such as Wi-Fi or Ethernet) and click "Advanced"
• Switch to the "DNS" tab
• Click the plus sign ( ) button in the lower left corner to enter the DNS address you want to use, such as Cloudflare's 1.1.1.1

If you are not sure what to fill in, you can try public DNS, such as Google, Cloudflare, and Alibaba Cloud all provide free services.

3. Where to change the DNS settings on the router?

If you want the devices in the entire LAN to go to the same DNS, it is easier to set them directly on the router.

• Log in to the router background (usually access 192.168.1.1 or 192.168.0.1 through the browser)
• Enter the account password to enter the management interface
• Find the DNS configuration item in Network Settings or WAN Settings
• Change the default automatic obtain to manual and fill in the DNS address you want

The interfaces of different brands of routers vary slightly, but you can basically find relevant options in "Network" or "Advanced Settings".

4. Is it convenient to change DNS on your mobile phone?

Both Android and iOS support manual DNS setting, but the methods are slightly different.

Android:

• Go to Settings → “Network and Internet” → “Wi-Fi”
• Click the currently connected Wi-Fi name
• Switch to "static IP" mode and fill in the address in DNS1 and DNS2

iPhone:

• Settings → Wi-Fi → Click the currently connected Wi-Fi
• Scroll to the bottom and click "Configure DNS" → select "Manual"
• Delete the default DNS and add the address you want

Some phones also support the use of private DNS (such as DNS over TLS), which can be enabled in the "Advanced" settings.

Basically these are the methods. Different devices operate slightly differently, but the overall idea is the same: find the network connection settings and manually specify the DNS address. Don't rush to save it when changing it, and then exit after confirming that the address is correct.
