Nice Program!
Thank you Shanmukha! We hope you stay connected with us and find some excellent C Programs on our website!
thank very hopefully this program bro.. but i want to automatically alert ip address .how to find that profram ..please tell that progrma
Can you explain it? Its unclear!
nice platform.. plz tell me about cryptography as well as hacking concept.
Hi,
nice program.
but i have a doubt. in my project i have an api url which used this piece of code to get public ip of a machine and that is running on lets say server A. And that api url is placed inside a separate web page which is running on server B. Now my question is… if I load the web page from different locations and different machines what will be the output of public ip?
my actual output: I am getting the public ip of server B where the web page is running.
expected output: i need to get the public ip of the particular machine on which the web page is loaded.
can anyone pls clarify it to me?
Thanks
can i get public ip address using java code (without url )
