Abstract:
In an embodiment, a dual stack (DS) client device (IPv4+IPv6) configures a header of a message for transmission to include a Via header with an IPv4 address of the DS client device, and transmits the configured message to a server via an IPv6 socket for transmission to a target client device. The target client device receives a message from a server in response to the configured message that identifies the DS capability of the dual stack client device based on a Via header that includes both IPv4 and IPv6 addresses. In another embodiment, a DS client device receives a message with a Via header configuration indicating IPv4 and/or IPv6 addresses through which another client device can communicate, identifies the other client device as DS, IPv4-only or IPv6-only based on the Via header configuration and selects a target format for communication with the other client device based on the identification.
