域名服务器(Domain Name System,简称DNS)和空间(通常指网站托管空间)之间的关系是紧密相连的,它们共同构成了互联网上网站访问的基础架构。
import dns.resolver
def query_dns(domain):
try:
answers = dns.resolver.resolve(domain, 'A')
for rdata in answers:
print(f'{domain} resolves to {rdata}')
except dns.resolver.NXDOMAIN:
print(f'{domain} does not exist.')
except dns.resolver.NoAnswer:
print(f'{domain} has no A records.')
except dns.resolver.Timeout:
print(f'Query timed out.')
query_dns('www.example.com')
通过以上信息,您可以更好地理解域名服务器和空间之间的关系,以及它们在互联网中的作用和应用场景。
