贴一个目前在用的 java 脚本..更新 mc 服务器的 ipv6 地址到 hosts
利用 git 推送 ipv6 地址到 github,然后其它机器同步写入 host

UpdateIp.java
-----------------------
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.nio.file.StandardOpenOption;

public class UpdateIp {
public static void main(String[] args) throws IOException {
var hosts = Paths.get("C:\\Windows\\System32\\drivers\\etc\\hosts");
var lines = Files.readAllLines(hosts, StandardCharsets.US_ASCII);
lines.removeIf(line -> line.endsWith("#yuki-mc-server"));

var ip = Files.readString(Paths.get("your-ip\\ip"), StandardCharsets.UTF_8);
lines.add("%s yuki-mc #yuki-mc-server".formatted(ip));

Files.write(hosts, lines, StandardCharsets.US_ASCII, StandardOpenOption.TRUNCATE_EXISTING);
}
}


update-ip.bat
-----------------------
cd your-ip
git pull
cd..
java UpdateIp.java
