多DNS批量解析域名

工作原因公司使用白名单的梯子访问方式，限制了可访问IP，一个个解析域名太麻烦，使用下面的python代码可以快速从多个DNS解析出需要访问域名的IP地址，代码如下：

import socket

def resolve_domain(domain, dns_servers):
    resolved_ips = set()

    for dns_server in dns_servers:
        try:
            ips = set(socket.gethostbyname_ex(domain)[-1])
            resolved_ips.update(ips)
            print(f"Resolved {domain} with DNS server {dns_server}: {', '.join(ips)}")
        except socket.gaierror:
            print(f"Failed to resolve {domain} with DNS server {dns_server}")

    return resolved_ips

if __name__ == "__main__":
    target_domains = ["openai.com", "ai.com", "challenges.cloudflare.com", "google.com","chat.openai.com","monica.im","accounts.google.com"]  
    # 编辑你想要获取IP的域名
    dns_servers = ["202.96.209.133", "114.114.114.114", "223.5.5.5", "8.8.8.8"]  # Add DNS server IPs you want to use here
    #编辑你需要去解析的DNS地址

    whitelist_file = "whitelist.txt"

    all_resolved_ips = set()

    for domain in target_domains:
        resolved_ips = resolve_domain(domain, dns_servers)
        all_resolved_ips.update(resolved_ips)

    with open(whitelist_file, "w") as f:
       for ip in all_resolved_ips:
            f.write(ip + "\n")
    print("Whitelist file created successfully!")

解析完后会在C:\Users\用户名\目录下生成一个whitelist.txt文件，就可以快速获得你需要的IP了。
