Do you offer domain registrations?
No, we are not a domain registrar. We provide DNS services for domains that you have already registered.

What Name Servers should I put in the Registrar Website?
Rexx Operates several DNS servers, you can put them all in your registrar record:

What happens when my domain goes over it's hit limit?
If you have our normal Paid DNS service our system will add a charge to your billing
for the overage at the end of the month. Currently Paid accounts include the first
1 Million hits, and we charge 10¢ for each additional 500k hits.

For Free DNS accounts, our servers will stop servicing your domain when it
goes over 25,000 hits. (You will get an E-Mail from our system when your domain goes
over 20,000 hits. Service will resume on the 1st of the following month, or if
you add paid DNS service to your account.

Do you offer load balancing?
Yes. Simply add multiple A records for the host with different IP addresses.
(ie: add TWO records with the "www" name with the different IP addresses.)
Our server will automatically serve the addresses in "round-robin" rotation.

Do you offer GeoDNS service?
No, however we do have a Geo-URL Redirect service that is included with our
paid DNS services. You will find the setup for GeoURL on the DNS setup page
of your Account Manager.
