### WHAT IS CHECKMYIP ### ### WHAT IS CHECKMYIP ###
Everybody has used a service like [WhatIsMyIP.com](https://www.whatismyip.com/) before. If you are an IT engineer or even an amateur technology enthusiast, then you have probably had a reason to check to see your public IP address. This service works great when a browser is available, but at times it is not. We often find ourselves logged into a remote Linux machine or a network switch/router which has a command line and terminal clients (Telnet and SSH), but no browser. The CheckMyIP app and the **TelnetMyIP.com** and **SSHMyIP.com** public services were created with this in mind.

If you are an IT engineer or even an amateur technology enthusiast, then you have probably had a reason to check to see your public IP address. This service works great when a browser is available, but at times it is not. We often find ourselves logged into a remote *BSD or Linux machine or a network switch/router which has a command line and terminal clients (Telnet and SSH), but no browser. The CheckMyIP app and the **myip.bsd.cafe** public services were created with this in mind.

### HOW TO USE ### ### HOW TO USE ###
Using the public **TelnetMyIP.com** and **SSHMyIP.com** services is pretty easy: simply connect to them with a terminal client. You can use a telnet client with TCP port 23 (`telnet telnetmyip.com`), a SSH client with TCP port 22 (`ssh sshmyip.com`), or CURL (`curl telnetmyip.com`). The SSH connection requires no authentication, but your SSH client may require you to enter a username, you can use anything you want as it gets ignored anyways(`ssh -limrootbitch telnetmyip.com`). Using the public **myip.bsd.cafe** service is pretty easy: simply connect to them with a terminal client. You can use a telnet client with TCP port 23 (`telnet myip.bsd.cafe`), a SSH client with TCP port 22 (`ssh myip.bsd.cafe`), or CURL (`curl -L myip.bsd.cafe`). The SSH connection requires no authentication, but your SSH client may require you to enter a username, you can use anything you want as it gets ignored anyways(`ssh -limrootbitch myip.bsd.cafe`).
You can also browse to the HTTP version of the service at [TelnetMyIP.com](http://telnetmyip.com/) which will return a JSON reply with your IP information. You can also browse to the HTTP version of the service at [myip.bsd.cafe](https://myip.bsd.cafe/) which will return a JSON reply with your IP information.
To enable the use of this service as a simple API, the response is formatted as a JSON document. See the [Using the API](#using-the-api) section for information on how to leverage the API.

**Note:** _You can also connect to_ `ipv4.telnetmyip.com` _or_ `ipv6.telnetmyip.com` _if you want to check a specific IP stack._
**Note:** _The DNS records for_ `telnetmyip.com` _and_ `sshmyip.com` _point to the same services._
