Hello Ivan, Michael, Daniel, > Isn't the returned address simply a IPv6-mapped IPv4 address (::ffff:1.2.3.4) ? You can test it with IN6_IS_ADDR_V4MAPPED. Yes, it is (I've verified with the provided macro) ! I'll use this macro to detect and update provided addresses, thanks ! Daniel, I'll try to test it on a recent kernel, but it will take some time to set up... thanks for the commit's reference !
