I would think that providers (like Yahoo or Google) who would like for you to install their mistyped-URL-handler in your browser would be rather upset at your ISP summarily preemting all of them. I would think that they stand to lose a LOT of $$ due to this scheme.
The place for these handlers is in browsers, not at the core Internet level.
BTW, with E-mail, it is true that SMTP servers will first do a MX lookup, but if that fails, they will then do an A lookup, which will never fail with this corrupted DNS.
And I wonder if there is a lawsuit in there somewhere due to the fraudulent assumption of authority over domains these ISPs don't own. | |

That is the exact problem that occurred when Verisign (who runs roots for .com) tried this very same thing a couple of years ago.
It was on a much larger scale, of course, since it applied to everyone everywhere, but email problems were rampant. Instead of immediate bounces for improper domains, suddenly every email domain appeared valid and would sit on queue for days before bounces would happen. Millions of sites were affected, and eventually most large ISPs had to override the A record and put those IP addresses on their ignore lists.
There are undoubtedly thousands of other applications that depend on NXDOMAIN responses being properly returned on invalid domains.
HTTP is not the Internet, and ISPs need to remember that. | |
