We pick m.root-servers.net, one of the 13 root servers (1), and ask it about dine.to and learn that to is delegated to five name servers (2), so we ask to.cctld.authdns.ripe.net where we learn that dine.to is delegated to two name servers, including dns1.tastemycity.com (3), so we ask that one and get the following answer:
Dine.to is a domain controlled by three domain name servers at tastemycity.com. All three of them are on different IP networks. Incoming mail for dine.to is handled by two mail servers at tastemycity.com and dine.to. Both are on different IP networks. Dine.to has one IP number (64.130.210.243), which also has a corresponding reverse pointer.
The two name servers dns3 and dns4.tastemycity.com together
There are eight domains that use name server group 1.
All of those use the primary name server dns3.tastemycity.com. Worth noting is that all of the domains that use the primary name server dns3.tastemycity.com use name server group 1.
