如何查域名对应的ip

nslookup example.com

dig example.com

import socket

def get_ip_address(domain):
    try:
        ip_address = socket.gethostbyname(domain)
        return ip_address
    except socket.gaierror:
        return "Could not resolve hostname"

domain = "example.com"
ip_address = get_ip_address(domain)
print(f"The IP address of {domain} is {ip_address}")

const dns = require('dns');

function getIpAddress(domain, callback) {
    dns.lookup(domain, (err, address, family) => {
        if (err) {
            callback(err);
        } else {
            callback(null, address);
        }
    });
}

const domain = 'example.com';
getIpAddress(domain, (err, ip) => {
    if (err) {
        console.error(err);
    } else {
        console.log(`The IP address of ${domain} is ${ip}`);
    }
});
