Name Servers

sim.dk carries NS records delegating to ns-master.csc.dk, ns1-auth.csc.dk and ns2-auth.csc.dk.

At least some of sim.dk's name servers are shared with other domains, for example gaeldst.dk, tastselvskat.dk, sanst.dk and two more.

These name servers are often deployed together with the name servers df-ns01.skat.dk, df-ns02.skat.dk, df-ns03.skat.dk and df-ns04.skat.dk.

Host names with two IP numbers:

ns1-auth.csc.dk resolves to two addresses: 147.29.236.25 and 2a01:5440:2:0:147:29:236:25.

ns2-auth.csc.dk resolves to two addresses: 147.29.238.25 and 2a01:5440:2:2000:147:29:238:25.
