网站域名解析是将人类易于记忆的域名转换为计算机能够识别的IP地址的过程。以下是域名解析的基本操作步骤、优势、类型、应用场景以及常见问题及解决方法:
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'{domain} does not exist.')
except dns.resolver.NoAnswer:
print(f'{domain} has no A records.')
except dns.resolver.Timeout:
print(f'Query timed out.')
resolve_domain('example.com')
