iOS: How to get the IP Address from Host name Objective C

- (NSString *)getIPAddress {
	Boolean result;
	CFHostRef hostRef;
	CFArrayRef addresses;
	NSString *hostname = @"www.google.com"; /*change to required host name */
	NSString *ipAddress = @"";
	hostRef = CFHostCreateWithName(kCFAllocatorDefault, (CFStringRef)hostname);
	if (hostRef) {
	result = CFHostStartInfoResolution(hostRef, kCFHostAddresses, NULL);
	if (result == TRUE) {
	addresses = CFHostGetAddressing(hostRef, &result);
	}
	}
	if (result == TRUE) {
	CFIndex index = 0;
	CFDataRef ref = (CFDataRef) CFArrayGetValueAtIndex(addresses, index);
	struct sockaddr_in* remoteAddr;
	char *ip_address;
	remoteAddr = (struct sockaddr_in*) CFDataGetBytePtr(ref);
	if (remoteAddr != NULL) {
	ip_address = inet_ntoa(remoteAddr->sin_addr);
	}
	ipAddress = [NSString stringWithCString:ip_address encoding:NSUTF8StringEncoding];
	}
	return ipAddress;
	}
