I have an NSNetService object and have resolved it. I need to find out the IP of the NSNetService so that I can use it in an AppleScript in a format like 192.168.1.1. Can someone please tell me how to do this. Thanks in advance.

I think this will do:

NSData *addressData = theNetService addresses] objectAtIndex:0];

struct sockaddr_in *socketAddress = (struct sockaddr_in *)[addressData bytes]; int firstOctet = (socketAddress->sin_addr.s_addr & 0xFF000000) » 24; int secondOctet = (socketAddress->sin_addr.s_addr & 0x00FF0000) » 16; int thirdOctet = (socketAddress->sin_addr.s_addr & 0x0000FF00) » 8; int fourthOctet = (socketAddress->sin_addr.s_addr & 0x000000FF) » 0;

[[NSString *ipAddress = [NSString stringWithFormat:@”%d.%d.%d.%d”, firstOctet, secondOctet, thirdOctet, fourthOctet];

You probably want the port number too:

UInt16 port = socketAddress->sin_port;

You will have to #import <sys/socket.h> and #import <netinet/in.h> for this to work.
