We pick g.root-servers.net, one of the 13 root servers (1), and ask it about sft-dev.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that sft-dev.com is delegated to three name servers, including ns01.softonic.com (3), so we ask that one and get the following answer:
Three quarter of the about twenty domains that use the mail server mx2.softonic.com use the two mail servers mx1 and mx2.softonic.com together, hereafter referred to as "mail server group 1", (example: softonic.com.br ).
The two mail servers mx1 and mx2.softonic.com together
Three quarter of the about twenty domains that use mail server group 1 point only to the IP number 46.28.209.20.
