as multicast addresses. Routers take care of making copies of datagrams and sending them to all receivers that have registered their interest in receiving targeted data. Anycast: Like broadcast and multicast, anycast is a one-to-many routing topology. However, the data stream is not transmitted to all receivers, just the one which the router decides is the "closest" in the network. Anycast is useful for balancing data loads. It is used in DNS and UDP.
