DNS delegation of stu.kashanu.ac.ir updated:


2stu.kashanu.ac.ir.ir.ns5.univie.ac.at. ir.cctld.authdns.ripe.net. a.nic.ir. b.nic.ir.
We pick d.root-servers.net, one of the 13 root servers (1), and ask it about stu.kashanu.ac.ir and learn that ir is delegated to four name servers (2), so we ask ns5.univie.ac.at where we learn that kashanu.ac.ir is delegated to three name servers, including ns2.kashanu.ac.ir (3), so we ask that one where we see a CNAME from stu.kashanu.ac.ir to webserver.kashanu.ac.ir, so we have to start all over again. We already know that ns3.kashanu.ac.ir is authoritative for kashanu.ac.ir (4) and ask it about webserver.kashanu.ac.ir and get the following answer:
