Cannot Connect To Httpbin.org In CMD

So I installed and enabled Telnet on my machine. I am using Windows 8 BTW. However, when I type in telnet httpbin.org 80, I get invalid command that follows this error. I am running CMD as administrator too. Does anyone know why I am getting this error?

I get invalid command that follows this error.

It'd be best that you post the full error message whenever you encounter one. But invalid command usually means that the Telnet on your system hasn't been properly configured or installed, as CMD doesn't seem to be able to locate this command.

Here's what my screen looks like when typing telnet httpbin.org 80 on admin CMD.

Connection to host lost.

I'm on Win10 by the way.
