-------------------
Dnstracer sends a non-recursive domain name request to the specified Domain Name Server.
Non-recursive requests mean that if the Domain Name Server knows, it will return request data.
If the Domain Name Server does not know, it will return the Domain Name Server of the authorization domain or the address of the Root Domain Name Server.
Command example:
Dnstracer www.mavetju.org
: Http://www.mavetju.org/download/dnstracer-1.9.tar.gz
