Fwd: Overlay broad patent on IPv6?

Nah what you describe is a different invention. Someone probably already has a patent on that. The browser will do a DNS lookup on slashdot.org and then cache that - forever (or until you restart the browser). Yes it will ignore the TTL (apps don't get the TTL at all, so apps don't know). Same happens if you ssh to yourserver.someplace.com. One DNS lookup, the traffic sticks there forever or until the session is terminated. DNS is horrible for this. If they had a IPv4 internal private network going you would not need to hook unto the DNS at all. Just get IP address when something wants to be routed out the WAN port. Also the NAT table is a good indicator of when you can release the address again. On other words, that would work, but the system described in the patent app wont. Of course both systems are useless. I can not imagine any end user that wont have a ton of IPv4 going on for the next decade to come. And when time comes, we are more likely to NAT64 than this.

The point is you'd already have a 192 address or something, and it would only grab the external address for a short duration for use as an external PAT address, thus oversubscribing the ip4 pool to users who need it (based on dns). Its still pretty broken, but less broken than you describe. On Mon, Jul 13, 2015 at 8:55 AM, <A.L.M.Buxey () lboro ac uk> wrote:Hi,This is actually a good idea. Roll out an IPV6 only network and onlypassout an IPV4 address if it's needed based on actual traffic.yes...shame someones applied for a patent on that! ;-) alan
