 EasyTier supports quick networking using shared public nodes. When you don't have a public IP, you can use the free shared nodes provided by the EasyTier community. Nodes will automatically attempt NAT traversal and establish P2P connections. When P2P fails, data will be relayed through shared nodes.
 
-The currently deployed shared public node is `tcp://public.easytier.cn:11010`.
-
 When using shared nodes, each node entering the network needs to provide the same `--network-name` and `--network-secret` parameters as the unique identifier of the network.
 
 Taking two nodes as an example (Please use more complex network name to avoid conflicts):

 Once your network is set up successfully, you can easily configure it to start automatically on system boot. Refer to the [One-Click Register Service guide](https://easytier.cn/en/guide/network/oneclick-install-as-service.html) for step-by-step instructions on registering EasyTier as a system service.

 #### 使用共享节点快速组网
 
-EasyTier 支持使用共享公共节点快速组网。当您没有公网 IP 时，可以使用 EasyTier 社区提供的免费共享节点。节点会自动尝试 NAT 穿透并建立 P2P 连接。当 P2P 失败时，数据将通过共享节点中继。
