Abstract

Methods, systems and computer program products provide for transferring a virtual Internet Protocol address (VIPA) between communication protocol stacks including at least a first communication protocol stack and a second communication protocol stack. Ownership of the VIPA is established at the second communication protocol stack and connections to the first communication protocol stack utilizing the VIPA are maintained. TCP/IP messages for the connections to the first communication protocol stack are routed through the second communication protocol stack so as to non-disruptively move the VIPA from the first communication protocol stack to the second communication protocol stack.
