Not really as a domain needs to point to a specific server by the use of Nameservers. (normally 2). It is the nameservers that point to the servers IP addresses.
You can have 1 million domains that all point to the same server as a domain is not a different name for an IP address. If this is what you think then you are in the wrong business and need to learn alot before to continue as a web host.
