(a,c,b).dns.gandi.net.
We pick k.root-servers.net, one of the 13 root servers (1), and ask it about opcions.com and learn that com is delegated to 13 name servers (2), so we ask k.gtld-servers.net where we learn that opcions.com is delegated to three name servers, including a.dns.gandi.net (3), so we ask that one and get the following answer:
Opcions.com is a domain controlled by three domain name servers at gandi.net having a total of six IP numbers. Some of them are on the same IP network. Incoming mail for opcions.com is handled by five mail servers at opcions.com themselves having a total of 42 IP numbers. There are 16 duplicated IP numbers. Some of them are on the same IP network.
