Dear All,
I want to change IP address via cocoa's API or other function.
Is anyone knows how to change IP in program?

Thanks!

Dear Ken,

My question is asking you why one would want to change an IP address in such a manner when there are so many things that factor into this that the end user does not have control over?

Thanks,

You could always do a shell out from your program to launch ifconfig with the required settings to change the ip address.

You can do this in Terminal.
sudo ifconfig en1 inet 192.168.0.1
And I imagine you can run a shell script via cocoa.

Thanks: Jane, blaster_boy & lancestraz:

Yes, shell script can work.
Do u have any other method to change IP address? like API or other functions?

Thanks :), not knowing this has led me to go via Applescript to do it :o, though it is a one-off usage so it's not a big deal.
