FAQ Why not use v4/v6 tunneling instead of NAT? tunneling would require a v4 address, which we may not have,not even in the 10/8 range Why not simply use double IPv4 NAT? same as above, 10/8 is too small for large deployments Why not deploy the home v6-only and translate directly to v4 in the home gateway? Will not help the legacy Win 9x boxes in the home What about new v6-only host trying to reach the v4 Internet? one problem at a time! Such device do not really exist today…. suggestion: use v6/v4 proxies in ISP network |
