DNS Proxy
SelectXpress offers its own DNS proxy server with a fixed IP address. The user should put this address in his resolving configuration and all his requests can be handled by SelectXpress Proxy DNS server.
The DNS Proxy forwards the request according to the current user profile to the appropriate DNS servers of the ISP or CP owning that part of the name space.
For the different states of a service (activated, subscribed etc.) different name servers can be given; thus the CP has full control which part of its name space is visible to the users in each state.
