An intranet is synonymous to a private LAN or WAN network but in contrast to the extranet or internet. Resources are retrieved and/ or shared within devices in the private network. It uses the internet protocol suite model of networking for communication, but also uses private IP addresses, which are not routable on the internet.
The communication between devices can be a peer to peer connection or client-server connection, using the mainframe computer technologies as the dedicated servers of the network.
