Analysis

Hierarchy

ac is the parent domain of unicorn.ac, iblt.ac, dlm.ac, ntu.ac, kaplan.ac and several thousand other host names.

Name Servers

ac has four authoritative name servers: a0.nic.ac, a2.nic.ac, b0.nic.ac and c0.nic.ac.

ac shares at least some of its name servers with other domains, such as nic.ac.

All four hostnames — a0.nic.ac, a2.nic.ac, b0.nic.ac and c0.nic.ac — resolve to two IP numbers apiece: a0.nic.ac to 65.22.160.1 and 2a01:8840:9e::1; a2.nic.ac to 65.22.163.1 and 2a01:8840:a1::1; b0.nic.ac to 65.22.161.1 and 2a01:8840:9f::1; c0.nic.ac to 65.22.162.1 and 2a01:8840:a0::1.
