We pick j.root-servers.net, one of the 13 root servers (1), and ask it about brainmindgym.com and learn that com is delegated to 13 name servers (2), so we ask h.gtld-servers.net where we learn that brainmindgym.com is delegated to two name servers, including ns03.domaincontrol.com (3), so we ask that one and get the following answer:
