How to figure out your IPv4 public IP from CLI (using TELNET). [TESTED]

This thing is known for decades, but the whole purpose of this post is for me to memorize new test public FTP server that I can use - []. The one that I used before for years is not working anymore.

All you need to do it so use any TELNET client (PuTTY for example). The only thing I noticed is when you use PuTTY you have to hit ENTER to get the prompt, then you can do user, pass, stat…

All you have to do is this:

telnet 21

user ftp
pass ftp

!!! You should see your public IP here !!!


Here is an example:

C:>telnet 21

220 (vsFTPd 3.0.3)
user ftp
331 Please specify the password.
pass ftp
230 Login successful.
500 Unknown command.
211-FTP server status:
     Connected to ::ffff:
     Logged in as ftp
     No session bandwidth limit
     Session timeout in seconds is 300
     Control connection is plain text
     Data connections will be plain text
     At session startup, client count was 58
     vsFTPd 3.0.3 - secure, fast, stable
211 End of status
221 Goodbye.

Good luck!
