My point was if you implement your proposal without doing a more classic ULA-C also, you will create demand for OUIs from the enterprise world just so they can get registered ULAs. There are not enough OUIs to satisfy that demand, and it would be a waste, too. So if you do an ULA-M you need to also do ULA-C to prevent those that would be happy with ULA-C from consuming vast numbers of OUIs only for the purpose of obtaining ULA. >> ULA (how about ULA-M, for ULA-Manufacturing) if it is created without a >> more standard ULA-C available for the enterprise guys. > > Yep, regards > Roland -- =============================================== David Farmer Email:far...@umn.edu Networking& Telecommunication Services Office of Information Technology University of Minnesota 2218 University Ave SE Phone: 612-626-0815 Minneapolis, MN 55414-3029 Cell: 612-812-9952 =============================================== -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
