如何搭建域名可用性检查器？

import requests
import dns.resolver
import time

def check_domain_availability(domain):
    try:
        response = requests.head(domain)
        return response.status_code == 200
    except requests.ConnectionError:
        return False

def get_domain_ip(domain):
    try:
        resolver = dns.resolver.Resolver()
        answer = resolver.query(domain)
        return [str(rdata) for rdata in answer]
    except dns.resolver.NXDOMAIN:
        return []

def run_domain_checker(domain, interval):
    while True:
        is_available = check_domain_availability(domain)
        ip_addresses = get_domain_ip(domain)
        
        print("域名: ", domain)
        print("可用性: ", "可用" if is_available else "不可用")
        print("IP 地址: ", ", ".join(ip_addresses))
        print("---------------------------")
        
        time.sleep(interval)

# 运行域名可用性检查器
run_domain_checker("example.com", 60)
