What is website service?
You can provide websites on your local network and over the Internet. A single server can run many different websites, each with its own Internet address (called a domain name) and method of serving webpages.
Before you begin
For this tutorial, you need to know a few things:
Who decides server names and manages the site’s domain name
This person could be you if you manage your network and server naming. If you're a member of a large organization, there should be someone (in an IT department, for example) who keeps track of server names and keeps them unique.
Who controls the router, gateway, or firewall that connects your network to your ISP
This person could be you if you’re using an AirPort Extreme Base Station to connect to a DSL provider, for example. If you’re a member of a large organization, there’s someone (in an IT department, for example) who keeps track of inbound and outbound web traffic and can assist you if your web server can’t be accessed over the Internet.
