how to get the external ip in objective c
6
i looked for some code that will help me to get the ip that the iphone connect with.
i find this one:
- (NSString *)getIPAddress
{
NSString *address = @"error";
struct ifaddrs *interfaces = NULL;
struct ifaddrs *temp_addr = NULL;
int success = 0;
// retrieve the current interfaces - returns 0 on success
success = getifaddrs(&interfaces);
if (success == 0)
{
// Loop through linked list of interfaces
temp_addr = interfaces;
while(temp_addr != NULL)
{
if(temp_addr->ifa_addr->sa_family == AF_INET)
{
// Check if interface is en0 which is the wifi connection on the iPhone
if([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"])
{
// Get NSString from C String
address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
}
}
temp_addr = temp_addr->ifa_next;
}
}
// Free memory
freeifaddrs(interfaces);
return address;
}
but the problem is that he get me this ip
10.0.0.1
there is any articlecode about getting the external ip.
thank you

What sort of IP address are you expecting? The device is likely to be going through a WiFi or 3G network, etc. hence you're not likely to be able to retrieve any form of meaningful "external" IP address.

Middaparka is right - from the device's viewpoint, 10.0.0.1 is its external IP address.

The easiest way to get your internet ip address from code is to use NSURLConnection.
For the URL you can use:
http://www.whatismyip.com/m/mobile.asp
or
http://checkip.dyndns.com/
Just parse the return data and you have your external ip address.

Unless you have like 10m DAU and call this every launch, then you really cost WhatIsMyIP.com A LOT of money in bandwidth for something that could be a local function. :o

What sort of IP address are you expecting? The device is likely to be going through a WiFi or 3G network, etc. hence you're not likely to be able to retrieve any form of meaningful "external" IP address.

Middaparka is right - from the device's viewpoint, 10.0.0.1 is its external IP address.
