networkInterface.getCarrierIPAddress() returns 0.0.0.0

[ezcliniq]

I am trying to log the public IP address of the client device when authenticating, but on carrier mode, I get IP address as 0.0.0.0, is this expected? Also on the wifi, I get the LAN IP and not the public IP.

What is the duplicate issue#?

I also noticed this issue is occurring for getWiFiIPAddress on an iPhone 8+. It is working on Android for me.

@MaddHatters I also face the same issue while getting getWiFiIPAddress. But I can able to fix it by doing some changes in CDVNetworkInterface.m file.

I printed all the interfaces that it is looping in getInterfaceiIP function which the result looks like this

[
  "lo0 :: 127.0.0.1",
  "lo0 :: 0.0.0.0",
  "lo0 :: 0.0.0.0",
  "en0 :: 0.0.0.0",
  "en0 :: 192.168.18.8",
  "en0 :: 0.0.0.0",
  "en0 :: 0.0.0.0",
  "awdl0 :: 0.0.0.0",
  "utun0 :: 0.0.0.0",
  "utun1 :: 0.0.0.0"
]

Where the getInterfaceIP function loops all the en0 entries and return the last value to the callback.

So to fix this add a condition to not to update the address variable when the entry contains 0.0.0.0 value.

example: add ![addr isEqualToString:@"0.0.0.0"] to the if check on getInterfaceIP

if([name isEqualToString:interfaceName] && ![addr isEqualToString:@"0.0.0.0"]) {
     // Get NSString from C String
     address = addr;
     subnet = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_netmask)->sin_addr)];
}

@ezcliniq for your case, I think this would be the root cause.

@sjnaveenkumar Interesting, and thanks for sharing. The issue on my end was the conversion of IPv6 to IPv4. The following PR was recently merged to handle that case.

When will this fix be updated to the npm package?

[salbahra]

I have added the check for 0.0.0.0 as suggested here and elsewhere. I will update the package soon with all the latest changes.

Thank you!
