What is name-based hosting? Do I need an IP address for each domain on my server?
Name based hosting is a method used to allow a server to host multiple domains with only one IP address. You do not need an IP address for each site; in fact, you only need one IP for the entire server. Name based hosting does not affect the performance or appearance of the domains hosted. Both Linux and Microsoft servers offer name based hosting. You should know that you are not limited to name based hosting, however. Extra IP addresses are available for no charge on most hosting accounts.
