Devise a program that will output the ip address of your computer?

Question

ipconfig is the command for getting the ip address

Use either C, js, c++

Answer 1

Just a note though, it is encouraged to not wave your IP address in public. Happy coding. :>

Answer 2

Yeah, my router admin address was bookmarked and I had many static IPs in my interfaces files. I also had a script. It was easier changing the router address XD

Didn't know about the 172.16.* to 172.31.* range, that was a surprise. Interesting. I only knew 10.* and 192.168.*.

Answer 3

On Linux in C:

/* Local network IPs - harmless */
#include <stdlib.h>
int
main (int argc, char **argv) {
/* Local network IPs
* Harmless
*/
system("ip address | grep inet");
system("echo ");
/* External IPs
* DO NOT post
*/
system("curl https://bot.whatismyipaddress.com");
system("echo ");
return 0;
}

Answer 4

system("ipconfig"); probably.

Answer 5

@Martin
That's why I provided a method for getting local network IPs (lo, eth, wlan) and one for your external IP and they both cheated with system(). Better shell tools.

PS: 192.168.8.* was my router's default for f.u.c.* knows why. Luckily changing it was built into the web UI.
