Analysis

Name Server Role

b.nameservercluster.net serves as a name server for idagroup.eu, nsc.ch, c.nameservercluster.com, b.nameservercluster.net, idagroup.net and a few other domains.

c.nameservercluster.com, a.nameservercluster.ch and ns1.vivanet.ch frequently serve as name servers alongside b.nameservercluster.net.

Mail Server Role

b.nameservercluster.net acts as its own mail server.
