It is not <vt_number> it is the display number of the X server running
and it starts counting from 0 so if you only have 1 X server running it
would be <my_ip_address>:0.  See the man X man page and the section on
Display Names.

You also need to give the remote machine permission to display on your
machine with the xhost command, see the man page. Usually 
'xhost +<remote_ip_address>' on the <my_ip_address> machine will work.
