DNS处理模块dnspython：是python实现的一个DNS工具包，利用其查询功能来实现dns的服务监控及解析结果的校验。常见的DNS解析类型包括A、MX、NS、CNAME。

# encoding:utf-8
import dns.resolver
 
# A记录的查询
def query_A(domain):
	result = dns.resolver.query(domain, 'A')
	for i in result.response.answer:
	    for j in i.items:
	    	print j.address
 
# MX记录的查询
def query_MX(domain):
	result = dns.resolver.query(domain, 'MX')
	for i in result:
		print 'MX preference =', i.preference, 'mail exchanger =', i.exchange
 
# CNAME记录的查询
def query_CNAME(domain):
	result = dns.resolver.query(domain, 'CNAME')
	for i in result.response.answer:
	    for j in i.items:
	        print j.to_text()
 
if __name__=='__main__':
	domain = "www.baidu.com"
	query_A(domain)
	# query_MX(domain)
