如何查服务器有几个域名

nslookup <服务器IP地址>

dig -x <服务器IP地址>

grep -r "ServerName" /etc/httpd/conf/

grep -r "server_name" /etc/nginx/

import dns.resolver

def get_domains_by_ip(ip_address):
    domains = set()
    try:
        answers = dns.resolver.resolve(ip_address, 'PTR')
        for rdata in answers:
            domains.add(str(rdata))
    except dns.resolver.NXDOMAIN:
        print(f"No PTR records found for {ip_address}")
    except dns.resolver.NoAnswer:
        print(f"No answer for {ip_address}")
    except dns.resolver.Timeout:
        print(f"Timeout for {ip_address}")
    return domains

if __name__ == "__main__":
    ip_address = "你的服务器IP地址"
    domains = get_domains_by_ip(ip_address)
    print(f"Domains associated with {ip_address}:")
    for domain in domains:
        print(domain)
