server-address
Set the server-address variable to the IP address for this domain.
When an incoming connection arrives, this domain's configuration is used
only if the IP address of the connection matches what you put here.
If the IP address does not match any of your configurations, the server
uses the first configuration as the default.
You may also use the fully-qualifed name (i.e. cse.unl.edu),
as long as this name will return the IP address when querying the nameserver
or hosts file.
Make sure each domain configuration uses a different value for
server-address!
Examples:
server-address=206.28.166.252
server-address=Elwood.probe.net
