A method in a data processing system for providing communication in a network with a plurality of channels, each of the channels with a plurality of nodes having an address stored in an address resolution component, the method comprising the steps of: assigning, by a secured access program, a multicast address to the plurality of nodes on one of the channels by transmitting the multicast address to the address resolution component; authenticating, by the address resolution component, the secured access program; responsive to successfully authenticating the secured access program, updating, by the address resolution component, the address of each node on the one channel to include the multicast address; sending a packet to the multicast address such that only the plurality of nodes on the one channel receive the packet; and deassigning the multicast address from the one channel such that the multicast address is rendered unavailable to the nodes on the one channel.
