(auth0,auth2,auth1).dns.openbox-ict.com.
We pick c.root-servers.net, one of the 13 root servers (1), and ask it about e.openbox-ict.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that openbox-ict.com is delegated to three name servers, including auth0.dns.openbox-ict.com (3), so we ask that one and get the following answer:
The primary name server auth0.dns.openbox-ict.com only
Eight of the ten domains that use the primary name server auth0.dns.openbox-ict.com use name server group 1. Worth noting is that all of the domains that use name server group 1 use the primary name server auth0.dns.openbox-ict.com.
