solution of this prob is simple,if you search for a domain name and
found that its unregistered then you should immediately registered
that domain :)

It's when you check the availability of a domain, find it's not taken, go
back in a day or two to register it, and it's taken. Probably by some shady
outfit like (in the case of my tests) Chesterton Holdings.


ICANN calls it "domain name front running"
(http://www.icann.org/committees/security/sac022.pdf). Last
year when I wrote about it
(http://www.eweek.com/article2/0,1759,1991365,00.asp) I
called it "whois hijacking"
 ICANN has heard reports of it, and while they're not sure there's anything
there, they agree that there is a perception there. Got that?

I know what I saw, so I know it can happen. I'm still not sure how this is
being done, but I think it's in small enough numbers that it's probably
being done through pinpoint compromises of servers here and there involved
in "Is this domain name available" web form. Could be the web server, could
be the DNS, could be some app server. Either that or someone is selling the
whois logs under the table.

I should also say I've gotten reports of this phenomenon from lots of people
who used many different services to check domain availability. I never spoke
to anyone who uses a command line whois talking to internic.net, but that's
not what most people do.
