We pick e.root-servers.net, one of the 13 root servers (1), and ask it about 1.9.10.10.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask b.in-addr-servers.arpa where we learn that 10.in-addr.arpa is delegated to two name servers, including blackhole-2.iana.org (3), so we ask that one and get the following answer:
