MX = dns.resolver.query('www.laosiji.com','MX') #指定查询类型为MX记录
for i in MX:
print('MX preference =',i.preference,'mail exchanger =',i.exchange)
#NS记录
def ns():
import dns.resolver
NS = dns.resolver.query(domain,'NS') #指定查询类型为NS记录
for i in NS.response.answer:
for j in i.times:
print(j.to_text())
#CNAME记录
def cname():
import dns.resolver
CNAME = dns.resolver.query('www.laosji.com','CNAME') ##指定查询类型为CNAME记录
for i in cname.response.answer:
for j in i.items:
