How are name based virtual hosts used in Apache?
Name-based virtual hosts The server does examine every matching virtual host in order of definition and selects which one should be used depending on the requested host name. This are called “name-based” virtual hosts. The first virtual host that matches the request is used.
Can a virtual host not specify a server name?
It is best to always explicitly list a ServerName in every name-based virtual host. If a VirtualHost doesn’t specify a ServerName, a server name will be inherited from the base server configuration. If no server name was specified globally, one is detected at startup through reverse DNS resolution of the first listening address.
What are the advantages of name based virtual hosts?
If there are no matches, the server does use the first defined VirtualHost as fallback. The main advantage of using name-based virtual hosts, is that we can run multiple websites on the same IP address. Let’s see an example of a name-based VirtualHost:
How are IP based virtual hosts used in httpd?
IP-based virtual hosts, as we already saw, are basically what the httpd server uses by default. When using them, the ability to serve multiple websites is based on the client request IP:PORT combination. It goes by itself that, to use this type of virtual hosts, a machine must have multiple network addresses.
How to disable all Apache virtual hosts in Debian?

Can a virtual host have the same IP address?
Above we can see that even if the two virtual hosts have the same IP address, a different port is specified in the second example: 8080. In order for the server to be able to listen to that port we use the Listen 8080 directive. In this tutorial we saw how Apache virtual hosts work.
