We pick e.root-servers.net, one of the 13 root servers (1), and ask it about a.nic.so and learn that so is delegated to three name servers (2), so we ask b.nic.so and get the following answer:
There are five domains that use the name server a.nic.so.
Four of those use the three name servers a, b and c.nic.so together.
One of them use the four name servers a, b, c and d.nic.so together (example: so ).
