According to this, vix.com shut down the service in 2007. Now vix.com redirects to domainnamesales, which I assume aren’t nice people.
The reason I noticed is this:
I tried to submit something to freedb.org, and it bounced because of maps.vix.com. So perhaps somebody … not very nice … finally decided to start answering in the affirmative to all requests?
In which case: Nicely played, scammers. This is probably going to drive a lot of traffic to your site while people are trying to figure out what’s going on.
