Hi everyone!
First of all, dnspython is a great tool and very useful, thanks!

We are having a problem using dns.query.xfr. It doesn't matter which
timeout value we use, every time we check a dns server that has the
53/TCP port filtered, the function waits 4 minutes before returning.

For example, we make this calls:

zone_transfer_data = dns.zone.from_xfr(dns.query.xfr(name_server, domain))

zone_transfer_data = dns.zone.from_xfr(dns.query.xfr(name_server, domain,10))

zone_transfer_data = dns.zone.from_xfr(dns.query.xfr(name_server,
domain,timeout=10))

or

zone_transfer_data =
dns.zone.from_xfr(dns.query.xfr(name_server,domain,
dns.rdatatype.AXFR, dns.rdataclass.IN, 00.00, 53, None, None, True,
None, None, None, 0, 0))


We want the function to return after few seconds, do you know what is
the problem? or how do we have to call the function?

thanks in advance!
