I’m looking for a script that does DNS/Domain error redirect. Thus, a toolbar is running in my browser, and when I input a URL that has a DNS problem, the toolbar throws my query to this script on a web server, and then presents me with suggestions (links, ppc ads, etc).
Roadrunner has it – here’s an example. See how they do spelling correction and try to determine what the user was seeking?
Anyone know of a script out there that does this?
Update: I found some answers, but not a script that I can just purchase. “NXD” means non-existent domain. Yahoo uses Simplicita (Sandvine now). Barefruit is another — and their wikipedia entry lists: Some of Barefruit’s competitors in the DNS error space include Nomimun (the founders of BIND), Paxfire, Golog, Simplicita (recently acquired by Sandvine) and OpenDNS.
