If you are installing WebSite Pro on a local area network, make sure your network administrator arranges for your computer to have a static IP address as well. Although you don t need the IP address during WebSite Pro installation, you will need it to make the server visible on the Internet or an intranet. Note As a slight twist, some intranets use computer names instead of static IP addresses or FQDNs. This setup also works for WebSite Pro, but we recommend you have a good understanding of NT networking before relying on this method. Hostnames are built from all the names necessary to reach a specific computer, which is what makes them fully qualified.
Domain names can refer to single computers or, more typically, a group of computers.
Thus, the additional information in the hostname is needed to locate the exact server. All rights reserved.
