Hi Jeroen Thanks for your answer.

Any sane operator would request and/or provide that. sgsstudentbostader.se. 300 IN A 46.239.65.2 sgsstudentbostader.se. 300 IN NS ns2.sgsit.se. sgsstudentbostader.se. 300 IN NS ns1.sgsit.se. ;; Received 140 bytes from 46.239.64.98#53(46.239.64.98) in 33 ms jeroen@noc:~$ dig +short @ns1.sgsit.se. www.sgsstudentbostader.se. any 46.239.65.68 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.
