One of my domains, teenshave.net is registred trough bulkdomains.com and also DNS is managed by them. I was just looking from Google if it's there or not (not really SE optimized yet) and I notised something VERY strange.
I searched for teenshave.net. It returned no results, but recommended on clicking if the domains exists. I did, and was taken to search.sprinks.about.com. Wow. Ok, then I typed in the teenshave.net manually and this time I was taken to my site.
Looking the DNS, it seems that teenshave.net doesn't have an A record (which I'm pretty sure I've defined, I always do that first).
Then I took another try, quitting the browser and restarting. This time teenshave.net was taken to mad2.net / enom.com.
www.teenshave.net works as it should.
Some pretty strange shit. Please, if someone has any clues, please let me know.
My guess:
bulkdomains.com (or group of companies) are doing the following:
they have tailored BIND which does a round robin for all the A records requested which don't exists. Then they sell this traffic. Some pretty funny stuff though..
