Please refer to your instruction letter that contains your username and password that you received when your order was processed.
Your DNS/nameserver information is listed in this letter.
This information changes daily and from site to site so there are no "standard" DNS details to give you.
If you are already hosted with us, and are trying to find this information out for reference, you can do a whois lookup on your domain. Try www.instapro.net for a whois lookup. Try to register your Domain name, it will tell you that it is registered already. Then click the option to view the details and it will list the DNS or nameservers that your domain is currently using.
if the above fails please contact support by logging in and submitting a trouble ticket to obtain information on your nameserver settings, or you can send an email to firstname.lastname@example.org if you are a registered user.
