This article explains how to use “free VPN nodes” and why issues such as an unchanged IP, DNS leaks, or abnormal browser environment settings may still occur after connecting. You can follow the steps below to import free nodes and use simple methods to check whether the connection is actually working.
1. What exactly are free VPN nodes?
Common free VPN nodes are usually proxy configurations such as V2Ray, VLESS, Trojan, and Shadowsocks. Users need to import them into clients like Clash, V2RayN, sing-box, and Shadowrocket before use. This site compiles available free nodes and subscription information, but free nodes are heavily affected by network conditions, routing quality, and the number of online users, so they are best treated as temporary options for learning, testing, or emergencies.
Nodes do not start working automatically after installation. A client must parse the node information and forward system or browser traffic through the corresponding proxy route. Although different clients have different interfaces, the core process is basically the same.
2. How to use free VPN nodes: general steps
- Choose a client: On Windows, you can use Clash Verge or v2rayN; on Android, v2rayNG or Clash Meta; on iOS, common options include Shadowrocket and Stash; on macOS, Clash Verge and sing-box graphical clients are available.
- Copy the node link or subscription address: common formats include vmess://, vless://, trojan://, and ss://, or it may be a subscription URL.
- Open the client, choose “Import from Clipboard,” “Import from URL,” or “New Subscription,” then paste and save.
- Update the subscription, select a node, and click connect or set it as the current proxy.
- Enable “system proxy” or choose rule mode. If you only want your browser to use the proxy, you can combine it with a browser proxy extension, but for most users, using the system proxy first is recommended.
- Visit an IP checking website and confirm that the displayed exit IP is different from your local ISP IP.
3. What to check for IP, DNS, and browser environment
After connecting to a proxy, the most obvious change is the exit IP. If the checking website still shows your local IP, it usually means the client has not enabled the system proxy, the node is not actually connected, or the browser is bypassing the proxy.
DNS is used to resolve domain names into IP addresses. In some cases, web traffic goes through the proxy, but DNS queries still go through the local network, which can cause a DNS leak. It is recommended to enable the client’s built-in DNS, rule-based DNS, or Fake-IP/TUN mode; the exact name varies by software. If you are only using a browser proxy extension, the chance of DNS leaks is much higher.
The browser environment also includes language, time zone, WebRTC, local cache, account login status, and more. Even if your IP has changed to an overseas one, the browser may still expose your local time zone or reveal your local address through WebRTC. Ordinary users can disable browser options related to WebRTC leaks or use browser extensions that support leak protection.
4. Troubleshooting connection failures and abnormal behavior
- Node import failed: check whether the link is complete, whether the subscription address can be opened normally, and avoid copying extra spaces or line breaks.
- Shows as connected but webpages will not open: switch nodes, update the subscription, try global mode, and then check your local firewall or security software.
- Only some websites can be opened: switch between rule mode and global mode, or change to a node that supports access to the required region.
- IP has not changed: make sure system proxy/TUN mode is enabled, and that the browser is not separately set to a direct connection.
- Abnormal DNS test results: enable the client’s DNS function, restart the client and browser, and test again.
Free nodes do not guarantee long-term stability. Timeouts, high latency, and frequent disconnections are all common. It is recommended to prepare multiple nodes and update subscriptions regularly. After completing checks for IP, DNS, and browser environment, you can basically determine whether the free VPN nodes are truly usable.
