Thread: Accessing internet from SQL

I used following command to access a website from SQL

select utl_http.request('http://www.geekinterview.com/') from dual;

It is showing message

The following error has occurred:

ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1568
ORA-12545: Connect failed because target host or object does not exist

Could any please suggest what is wrong with above command?

Please find about utl_http here ,here and here.
