ABSTRACT:
An IPv4-IPv6 multicast address translation table is dynamically created, so that it is unnecessary to register multicast servers in advance. When an IPv4 MC group address exists as a response of a DNS server to a DNS request of an IPv6 MC client or when an IPv6 MC group address exists as a response of the DNS server to a DNS request of the IPv4 MC client H1to H4, DNS Proxy D3requests an MC adaptive translator T1to generate a virtual IPv6 MC group address or a virtual IPv4 MC group address, and the MC adaptive translator T1generates a virtual IPv6 MC group address or a virtual IPv4 MC group address from an address pool, and also creates an MC address translation table, whereby the MC address translation of IPv4-IPv6 can be dynamically performed.
