如何从Python中的IP地址获取NAPTR记录？

Question

I'm looking to do something like this in python using dnspython:

 dig @XXX.YYY.ZZZ.AAA -p 99 +short '1.1.1.1.1.1.1.1.1.1.1.e164.arpa' naptr

I thought dns.resolver.query would be the way to go, but it seems to choke on the IP address.

My code:

for rdata in dns.resolver.query('XXX.YYY.ZZZ.AAA', 'NAPTR') :
print rdata.target

Output from running the code:

  Traceback (most recent call last):
  File "...\src\dnslookup.py", line 12, in <module>
    for rdata in dns.resolver.query('XXX.YYY.ZZZ.AAA', 'NAPTR') :
  File "build\bdist.win-amd64\egg\dns\resolver.py", line 920, in query
  File "build\bdist.win-amd64\egg\dns\resolver.py", line 856, in query
dns.resolver.NXDOMAIN

As OXC pointed out, your code is querying for the NAPTR record for XXX.YYY.ZZZ.AAA which is not the equivalent to your dig command.

Here is code that more closely matches your dig command:

resolver = dns.resolver.Resolver()
resolver.nameservers = ['XXX.YYY.ZZZ.AAA']
resolver.port = 99

resolver.query('1.1.1.1.1.1.1.1.1.1.1.e164.arpa', 'NAPTR')
# Need to confirm syntax for NAPTR query
