I have a website and related services running under a Rackspace's Cloud Load Balancer. In my DNS setting I have pointed my domain (say example.com) to the IP of this load balancer and it works fine.
The problem am facing is that someone has pointed their domain (say example.net) to my load balancer. So now am able to access my website through both example.com and example.net
I know we can restrict this kind of things when using Nginx/Apache but not sure how to avoid this when using Rackspace's Cloud Load Balancer.
