I am happy to accept an answer of, "Yes, > all 1918 address space is used by such equipment", but > nobody, including you, has actually said that. one reason enterprises use 172.16/12 for stuff is because that way, when their VPNs come up with people's residents, they do not immediately conflict with the LAN at the home/coffee shop, etc. And, there is a further consideration: this space only has to be useable to for CGNs, for ISPs that have new customers that they want to hook up via IPv4. Most of these ISPs already provide a home gateway (often integrated with the DSL model or cable modem), and it only has to work with that brand! So I favour 172.16/12 or 224/10. -- ] He who is tired of Weird Al is tired of life! | firewalls [ ] Michael Richardson, Sandelman Software Works, Ottawa, ON |net architect[ ] mcr@xxxxxxxxxxxxxxxxxxxxxx http://www.sandelman.ottawa.on.ca/ |device driver[ Kyoto Plus: watch the video <http://www.youtube.com/watch?v=kzx1ycLXQSE> then sign the petition.
