怎样解析dns地址用代码

const dns = require('dns');

dns.lookup('www.example.com', (err, address, family) => {
  if (err) throw err;
  console.log(`IP address: ${address}`);
});

import socket

try:
    ip_address = socket.gethostbyname('www.example.com')
    print(f'IP address: {ip_address}')
except socket.gaierror as e:
    print(f'Error resolving DNS: {e}')

import java.net.InetAddress;
import java.net.UnknownHostException;

public class DnsResolver {
    public static void main(String[] args) {
        try {
            InetAddress address = InetAddress.getByName("www.example.com");
            System.out.println("IP address: " + address.getHostAddress());
        } catch (UnknownHostException e) {
            System.err.println("Error resolving DNS: " + e.getMessage());
        }
    }
}

using System;
using System.Net;

class DnsResolver
{
    static void Main()
    {
        try
        {
            IPAddress[] addresses = Dns.GetHostAddresses("www.example.com");
            foreach (IPAddress address in addresses)
            {
                Console.WriteLine($"IP address: {address}");
            }
        }
        catch (Exception e)
        {
            Console.WriteLine($"Error resolving DNS: {e.Message}");
        }
    }
}
