We will use dnspython for the DNS zone transfer.
Listing 11.4 gives a simple code for a zone transfer as follows:
#!/usr/bin/env python
# Python Network Programming Cookbook, Second Edition -- Chapter - 11
# This program is optimized for Python 2.7.12 and Python 3.5.2.
# It may run on any other version with/without modifications.

def main(address):
soa_answer = dns.resolver.query(address, 'SOA')
master_answer = dns.resolver.query(soa_answer[0].mname, 'A')
try:
z = dns.zone.from_xfr(dns.query. xfr(master_answer[0].address, address)) names = z.nodes.keys() names.sort() for n in names: print(z[n].to_text(n)) except socket.error as e: print('Failed to perform zone ...
