批量生成二级域名是指通过自动化脚本或程序,一次性创建多个子域名。这些子域名通常是基于一个主域名(如 example.com
),并附加不同的前缀或后缀(如 blog.example.com
、shop.example.com
)。
www.example.com
、blog.example.com
。user123.example.com
。en.example.com
、zh.example.com
。shop.example.com
、news.example.com
。原因:
解决方法:
import dns.resolver
def create_subdomains(base_domain, prefixes):
subdomains = [f"{prefix}.{base_domain}" for prefix in prefixes]
for subdomain in subdomains:
try:
answers = dns.resolver.resolve(subdomain, 'A')
print(f"Subdomain {subdomain} resolved successfully: {answers}")
except dns.resolver.NXDOMAIN:
print(f"Subdomain {subdomain} does not exist.")
except dns.resolver.NoAnswer:
print(f"Subdomain {subdomain} has no answer.")
except dns.resolver.Timeout:
print(f"Subdomain {subdomain} timed out.")
# 示例使用
base_domain = "example.com"
prefixes = ["blog", "shop", "news"]
create_subdomains(base_domain, prefixes)
通过以上方法,可以有效地批量生成和管理二级域名,并解决常见的DNS解析问题。
