Well, how do you qualify a PC running a software component like Microsoft's "Internet Connection Sharing"? It appears as a host to the ISP, and acts as a router for the local network. That software has been available since at least 1998. But never mind PC. How do you qualify a home NAT that appears as a host to the ISP, get an IPv4 address using DHCP, and then appears as a router to the local network? There are millions of these. So what exactly is "well established"? -- Christian Huitema -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
