"First ping the nameservers that were given to you in your welcome email to get the IPs that are allocated to them. Once you have done this, go to your registrar and configure them as below:
ns1.yourdomain.tld ==> [using the IP of the 1st name server we gave you]
ns2.yourdomain.tld ==> [using the IP of the 2nd name server we gave you]
Once that is done open a ticket to the sales department and then we can go ahead and make sure the necessary A records are created on the server for you to use. Please not that it could take a few hours for the DNS to fully propagate but when all is said and done you should be set."
