We pick k.root-servers.net, one of the 13 root servers (1), and ask it about mobile.livio.com and learn that com is delegated to 13 name servers (2), so we ask g.gtld-servers.net where we learn that livio.com is delegated to four name servers, including ns4.livio.com (3), so we ask that one and get the following answer:
About one in six of them use name server group 2 (example: livio.com.do, domingo.org and lavega.net ). Worth noting is that half of the domains that use name server group 2 point only to the IP number 63.247.69.130.
There are about fourty domains that use the name server ns3.livio.com.
Three quarter of those use name server group 2.
Half of them point only to the IP number 63.247.69.130.
Six of them use name server group 4.
Five of them use mail server group 1.
The four name servers ns3, ns4, ns6 and ns7.livio.com together
Half of the about fourty domains that use name server group 2 point only to the IP number 63.247.69.130. Worth noting is that about one in six of the host names that point only to the IP number 63.247.69.130 use name server group 2.
