Question

Does anyone knows how can i detect from an app the DNS of the iPhone?

UPDATE: If there’re different ways of obtaining the DNS server and DNS host name, any solution is acceptable.

Answer 1

To get the host name you can use libc API, gethostname:

#import <unistd.h>

...

char hostname[HOST_NAME_MAX];
int err = gethostname(hostname, HOST_NAME_MAX);
if(!err)
    NSLog(@"My hostname is %s", hostname);
