We pick h.root-servers.net, one of the 13 root servers (1), and ask it about ww.fs-wy.net and learn that net is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that fs-wy.net is delegated to two name servers, including ns2.idc1.cn (3), so we ask that one and get the following answer:
Four percent of them use only the mail server mx125.72dns.net.
Three percent of them use only the mail server mx115.72dns.net.
Three percent of them use mail server group 1.
