setup sentora in my VPS server

i have purchased a vps server and istalled sentora panel on it , everything works fine and ihave generated the sentora logins,. i tried to log into the panel using the link http://vps83187.hostsailor.com generated but it seems not working and i think that i need to set up a subdomain pointing to my vps IP address , i need some one who can manage dns records for the sub domain so i can access the panel on my browser.
