The above command could be simplified to:
scp 192.168.0.4:boxinfo.html .
You’d need to specify a remote user only if connecting to the remote host as a different user. Likewise, you only need specify a remote directory if it is not the home directory of the user you are connecting as. Finally, the local directory need be specified only if it is not the current directory.
