We are adding tens of thousand IPv4 addresses using netlink interface without any problems. The maximum we added was 60K of secondary IPv4 addresses. It consumes some memory, however. We have also added thousands of IPv6. I will try to test, if there is any limit for doing it. -- Sincerely, Robert Iakobashvili, coroberti %x40 gmail %x2e com ........................................................... http://curl-loader.sourceforge.net A web testing and traffic generation tool. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
