IP-based and name-based Web sites
IP-based and name-based Web sites.
There are two ways to host domains. The first is to create the domain with its own IP address. This is called IP-based hosting. You must create IP-based domains if the domain needs anonymous FTP and its own secure-site (SSL) support.
The second way to host domains is to create a domain that shares the primary IP address of the server. This is called name-based hosting. Name-based domains receive most of the benefits of an IP-based domain without occupying an IP address.
All of the standard sets of server applications are available to IP-based and name-based sites, except SSL encryption. SSL is not supported for name-based sites.
IP addresses happen to be scarce resources. To conserve IP addresses, you can arrange to have many sites share the same IP address.
