Overlay broad patent on IPv6?

Mon Jul 13 15:54:49 UTC 2015

Too bad it won't actually work. I type Slashdot.org in my browser. The web
browser does DNS lookup. The CPE notices there is only an A record
available and boots the IPv4 stack. However there is no way to push an IPv4
configuration to my computer. DHCP is pull not push. Even if there was, the
web browser would not be prepared for an IPv4 configuration to suddenly
appear in the middle of a request.

I notice the patent application does not actually specify how this is
supposed to work. It should not be possible to patent without building a
prototype and indeed without even knowing how to build one. Then if someone
later figures out the details, you somehow owe your soul to these guys that
just did some handwaving.
