Python查询域名的IP地址的实现

python --version

import socket

# 查询域名的 IP 地址
domain = 'example.com'
ip_address = socket.gethostbyname(domain)

# 输出 IP 地址
print(f"The IP address of {domain} is {ip_address}")

import socket

# 查询域名的所有 IP 地址
domain = 'google.com'
host_info = socket.gethostbyname_ex(domain)
ip_addresses = host_info[2]

# 输出所有 IP 地址
print(f"The IP addresses of {domain} are: {ip_addresses}")

import socket

def get_ip_address(domain):
    try:
        return socket.gethostbyname(domain)
    except socket.gaierror:
        return None

domains = ['example.com', 'python.org', 'google.com']

for domain in domains:
    ip_address = get_ip_address(domain)
    if ip_address:
        print(f"The IP address of {domain} is {ip_address}")
    else:
        print(f"Could not resolve {domain}")

import socket
from concurrent.futures import ThreadPoolExecutor, as_completed

        return socket.gethostbyname(domain)
    except socket.gaierror:

domains = ['example.com', 'python.org', 'google.com']

# 使用多线程处理域名查询
with ThreadPoolExecutor(max_workers=10) as executor:
    futures = {executor.submit(get_ip_address, domain): domain for domain in domains}
