hehe
really lame
or maybe i don't understand
i think first operating system looks hosts file and then (if not true) makes
a dns query
its not a bug or vulnerability
it is feature (which came from ancient times when there was no domain name
system on the Earth)
i think it is not a topic for this list
i can create zone file for microsoft.com on my ISP master NS server with
entry like this
www IN A 127.0.0.1
and it will work BUT I WILL NOT WRITE about this in bugtraq !!
forgive me my bad english, usually i only read bugtraq, but now after this
message i can't be silent ;)
