dns.resolver.query(domain,'NS') - bad answer

[Peter Václavek]

I encountered problem with answer from dns.resolver.query. When Im asking NS record for from domain 004.sk it responds with bad answer.
This occurs just with this specific domain: 004.sk

answers = dns.resolver.query('004.sk', 'NS')
print answers[0]

Output:
fivestar.

Expected Output:
ns1.fivestar.sk

With other domains I havent met with this problem.

The problem is not with dnspython, but with one of the authorities, ns1.fivestar.uk:

$ dig @ns1.fivestar.sk. 004.sk. ns

; <<>> DiG 9.8.3-P1 <<>> @ns1.fivestar.sk. 004.sk. ns

; (1 server found)

;; global options: +cmd

yes, you are right. I apologize, I didnt expected that it might be a problem on the side of authorities.
