A disclosed information processing apparatus, which is used in a multi-tenant network connected to the relay apparatuses, includes: an allocation unit that allocates, upon receipt of an allocation request including a first multicast address and a first tenant identification information from a relay apparatus, a second multicast address that is a multicast address, which is not allocated to any multicast domains, to a multicast domain identified by a combination of the first multicast address and the first tenant identification information; and a transmission unit that transmits the second multicast address to at least the relay apparatus that is a transmission source of the allocation request.
