AI analysis

Host names instagram.courses, edu.courses, com.courses, lexicom.courses, hdmovie2.courses and several others have courses as their parent.

The delegation of courses is to six name servers, namely a.nic.courses, b.nic.courses, c.nic.courses, x.nic.courses, y.nic.courses, and z.nic.courses.

The name servers of courses are at least partially shared with other domains, such as nic.courses.

a.nic.courses, b.nic.courses, c.nic.courses, x.nic.courses, y.nic.courses, and z.nic.courses all point to two IP numbers each: 2001:dcd:1::9 and 37.209.192.9, 2001:dcd:2::9 and 37.209.194.9, 2001:dcd:3::9 and 37.209.196.9, 2610:a1:1074::1:82 and 156.154.172.82, 2610:a1:1075::1:82 and 156.154.173.82, 2610:a1:1076::1:82 and 156.154.174.82 respectively.
