We pick j.root-servers.net, one of the 13 root servers (1), and ask it about yesky.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that yesky.com is delegated to three name servers, including dns3.yesky.com (3), so we ask that one and get the following answer:
Three of them use the three name servers dns1, dns2 and dns3.yesky.com together, hereafter referred to as "name server group 2", (example: tvmeinv.cn ).
The two name servers dns1 and dns2.yesky.com together
There are about twenty domains that use name server group 1.
Four of those use only the mail server mail.yesky.com. Worth noting is that four of the domains that only use the mail server mail.yesky.com use name server group 1.
Three of them point only to the IP number 219.239.91.198.
Three of them point only to the IP number 219.239.88.202.
Four of the five domains that only use the mail server mail.yesky.com use name server group 1. Worth noting is that four of the domains that use name server group 1 use only the mail server mail.yesky.com.
The name server dns3.yesky.com
All of the three domains that use the name server dns3.yesky.com use name server group 2.
