If you want some zone files parsed let me know. I do it frequently and can easily throw in a couple nameservers and parse the list in a few minutes for you if you are looking to see what names someone owns.
That is nice of you JDK, thanks :yo:
Don't need it at this time. I have a feeling that it would be very hard to figure out for the reason that someone mentioned above, several of these companies are in "stealth mode" because some of their best domains are typo's and they don't want to appear to be deep pocket litigation targets.
NameMedia admits to have been in "stealth mode" until recently. I'm guessing NameMedia has less typo domains than the other big dogs.
