如何获取o.s的当前名称服务器。从nodejs？

const os = require('os');

// 获取当前名称服务器
function getCurrentNameservers() {
  const interfaces = os.networkInterfaces();
  let nameservers = [];

  Object.values(interfaces).forEach(iface => {
    iface.forEach(addr => {
      if (addr.family === 'IPv4' && !addr.internal) {
        nameservers = nameservers.concat(addr.address);
      }
    });
  });

  return nameservers;
}

// 调用示例
const nameservers = getCurrentNameservers();
console.log('当前名称服务器:', nameservers);
