Intranet. An intranet is an internal network. People use the intranet to communicate and share content with each other. While it’s common for an intranet to include web servers, this isn’t a requirement. • Extranet. An extranet is part of a network that can be accessed by authorized entities from outside of the network. For example, it’s common for organizations to provide access to authorized business partners, customers, vendors, or others.
