DNS delegation of yesky.com updated: Jun 19, 2013 2:28:19 AM
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:
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.
