Abstract: A method and system of virtual multicasting content is disclosed. The method and system disclosed enable the receipt of virtual multicast content without requiring the expensive investment in the infrastructure necessary for a network to be multicast enabled. The virtual multicasting may be performed according to a method of virtual multicasting multicast content on non-multicast enabled networks, comprising the steps of determining if an attached network is multicast enabled, if the attached network is not totally multicast enabled, querying for virtual multicast requests for the multicast content from non-multicast enabled client computers, listening for virtual multicast requests, and determining, based on the virtual multicast requests, which client computers request the multicast content, from the unicast addresses, and the requested methods of delivery for the multicast content.
