For my project, i need to get the IPhone's Public IP address, there are so many examples available, which show public IP address by using external / third party URL. I just want to know how to extract IPhones's IP Address without help of using another url.

Note :- I used This one but shows only the local IP address , i need public IP address

 func getIPAddress() -> [String] { var addresses = [String]() // Get list of all interfaces on the local machine: var ifaddr : UnsafeMutablePointer<ifaddrs> = nil if getifaddrs(&ifaddr) == 0 { // For each interface ... for (var ptr = ifaddr; ptr != nil; ptr = ptr.memory.ifa_next) { let flags = Int32(ptr.memory.ifa_flags) var addr = ptr.memory.ifa_addr.memory // Check for running IPv4, IPv6 interfaces. Skip the loopback interface. if (flags & (IFF_UP|IFF_RUNNING|IFF_LOOPBACK)) == (IFF_UP|IFF_RUNNING) { if addr.sa_family == UInt8(AF_INET) || addr.sa_family == UInt8(AF_INET6) { // Convert interface address to a human readable string: var hostname = [CChar](count: Int(NI_MAXHOST), repeatedValue: 0) if (getnameinfo(&addr, socklen_t(addr.sa_len), &hostname, socklen_t(hostname.count), nil, socklen_t(0), NI_NUMERICHOST) == 0) { if let address = String.fromCString(hostname) { addresses.append(address) } } } } } freeifaddrs(ifaddr) } return addresses }

I used this one in my swift project by using a header file, it generates Local IP

Reset to default

let address = try? String(contentsOf: URL(string: "https://api.ipify.org")!, encoding: .utf8) print(address)

Then you get public IP-address

prints on my own computer

List of IP addresses on host Ivos-MacBook.local IPv6: fe80::225:ff:fe40:9c72 IPv6: 2a02:130:200:1350:225:ff:fe40:9c72 IPv4: 192.168.1.106

for external IP, you need help of external service (not swift specific :-))

Thanks for the code, But the problem is this shows phone IP, I need to get the Iphone public IP, to IP location and related data. :(
What do you mean by talking about 'public' IP? the code lists all public IPs (IP via which the device is accessible in your LAN). it seams you are looking for the way how yo get external IP of your device. as i sad, you need help of external service for that. I recommend you to read en.wikipedia.org/wiki/Network_address_translation
Yeah , I don't want to use external service. I need an internal coding solution, That's the problem. because can't rely on external services.
are you looking for your external IP?
Yeah public Ip where i can extract the location of the phone by using it's external IP address
