Name Servers

didactica.dk is served by two delegated name servers, ns2.scannet2.dk and ns.scannet2.dk.

didactica.dk uses the same name servers as several other domains — among them olseen.dk, ynot.dk, xresource.dk and two more.

didactica.dk shares at least some of its name servers with other domains, including it-cloud.dk, scarletscan.com, copcap.com and two others.

These name servers are frequently seen alongside the name servers ns3.scannet2.dk.

Each of the two host names carries two IP addresses: ns2.scannet2.dk points to 91.197.248.72 and 2a02:2339:1:112:0:5:1:b11, and ns.scannet2.dk points to 185.25.141.9 and 2a02:2339:4006:10d::4171:4171.
