Nice one Amulya - just a TLDR for others, if you are using latest (and or beta) versions of High Sierra on Mac, telnet is no longer included by default. Provided you have homebrew installed on your Mac (https://brew.sh/), it's a simple call to:

MacBookAir:~ username$ brew install telnet

After telnet has installed you will be able to run the example from the commandline:

MacBookAir:~ user$ telnet httpbin.org 80
Trying 50.16.223.157...
Connected to httpbin.org.
