WordPress Multisite is one of the greatest features that allows having all your sites within one WordPress installation. It also has domain mapping feature that allows for mapping of domain to each multisite subsite. This implies that a WordPress subsite created either as subdomainsubsite1.netdomain.com or as a subdirectorynetdomain.com/subsite1 could be mapped to display as domaindomain.com.
