DNS(Domain Name System,域名系统)解析器是一种将人类可读的域名转换为计算机可识别的IP地址的服务。它是互联网基础设施的关键部分,使得用户可以通过易于记忆的域名来访问网站和其他在线服务。
import dns.resolver
def resolve_domain(domain):
try:
answers = dns.resolver.resolve(domain, 'A')
for rdata in answers:
print(f'{domain} resolves to {rdata}')
except dns.resolver.NXDOMAIN:
print(f'The domain {domain} does not exist.')
except dns.resolver.NoAnswer:
print(f'The domain {domain} has no A records.')
except dns.resolver.Timeout:
print(f'The query for {domain} timed out.')
resolve_domain('www.example.com')
