Ok, if I understand this from a hardware (not application) point of view a company like IBM (or any other large company with multiple sites) will be required to pay an upstream provider for (private) local IP addresses for their printers. Think about it, at the hardware side of this we are encouraging them to keep using IPv4 for those items that will not be connected to the public internet. Or to look at it another way, the Macintosh computers on a LAN that used to broadcast a request for every printer on a network whenever the printer dialogue box was opened. With no local distinctions then entire WAN will be polled for printers, if not the entire Internet. We need to find some way to filter or block this kind of activity. -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
