Hi Jeroen
Thanks for your answer.
Where is your 'dig' output? Any sane operator would request and/or provide that.
Sorry, I thought the details a not important for the list, because the problem is on the remote site.
Here they are:

Google was not able to answer this question?
Likely as you are asking the wrong question ;)
Some time it is difficult to ask the right questions ;-)

Hi all,
The dns resolvers of ETH Zürich are not able to resolve names within the domain sgsstudentbostader.se. As far as I can see, it is a connection Problem. The Problem is located on the remote site.
Where is your 'dig' output? Any sane operator would request and/or provide that.

Put that in /etc/hosts for a short time and you can at least browse their site.
Of course if you can't reach their prefix (46.239.64.34/24) you are out of luck, and that would also explain why you can't resolve anything, some silly people still think it is smart to have all eggs in one basket^Wprefix.
(and if you would have provided the dig output and related traceroutes for destinations that could have been unreachable, you would have had your answer already what was wrong ;)
I would like to contact the operator of the domain sgsstudentbostader.se.
I tried the email-addr from the SOA record, without success.
Typically those are not read or too heavily spammed causing them to be not read unfortunately.
Does anybody on the list know if an e-mail list similar to swinog exists in Sweden?
