How can I know the IP address of my iPhone simulator?
It will have the same IP addresses as the computer you’re running it on.
Jep, like Todd said, the same as your machines IP. You can also simply visit http://www.whatismyip.com with mobile Safari or your Mac's web browser ;-)
I think the by visiting the website http://www.test-ipv6.com/ is also a good choice. As the site tells you both the ipv4 and ipv6 global-unicast address

I'm working on a web application and need to debug a problem occurring only on the iPhone.
I can reach the site on my dev box by typing its ip address into Safari (on my phone), but the domain is significant to the application, so I'm going to have to update my config in multiple places every time my IP changes.
What would be ideal is if I could configure the iPhone to always point to a specific IP when I enter a specific domain, just like the C:\Windows\System32\Drivers\etc\hosts file.
Is there a way to do that without jail breaking my phone?
You'd have to jailbreak your iPhone, another way would be to use a proxy. Hope I could help :)
If you have jailbroken, I think it's /etc/hosts (same as the Mac OS X setup)
I appended .local to the end of my computer name and it was able to resolve it.
It's not a perfect solution since I'll still have to adjust the settings in the app, but at least I won't have to keep changing it when my IP changes.
According to this answer on another SE site, it's Bonjour functionality.
I am working on IPhone. I want to know how to find a ip address of a iphone through USB/3G not on wifi.
I am aware of seeing IP if it is connected through WiFI.(Going through settings and looking under Wifi)
But i need IP through USB / 3G. what i did means i used personal hotspot and i connected my iphone to PC through usb. I got an IP.
But when i added one more Iphone with same hot spot enabled and connected through USB i am getting like unidentified network.
By using whatismyip.com site i am getting an ip . but i cant do anything with it. I am unable to reach my iphone with the provided ip of that site.
So can anyone kindly provide information on how to look for IP of multiple Iphones connected to same PC.
The purpose is to communicate to muliple iphones with their IP's.
Thanks a million in advance.
Unfortunately the responses are not completely correct. In a 3G/4G network every device gets an IP address, but THAT's NOT the IP address that you see when going to sites like www.whatismyip.com. That's the address that the Telco presents to the external world, not the device IP address.
Telcos such AT&t, Verizon, Telefonica and similar assign a "private" IP address that is only valid in their network. This is similar to the internal IP address that you have in your phone when connect to the house wireless, but if you check in www.whatismyip.com you get the external IP address of your wireless router (You can check that those are different addresses). What Telcos do is known as NAT or PAT. The reason is that the current version of IP has a very limited number of available IP addresses, and all those million of devices cannot get public IP addresses (like the one you see in whatismyip.com). Actually several devices share that external IP address.
Unlike Android devices where you can get the IP that the telco assigned to the device, iOS does not present that information to the user (unless you jailbreak the device or have an App).
Although the address that whatismyip presents is not your real IP, it is the one that the external world recognizes so it suffices for most purposes.
What you see on whatismyip.com is the IP address you get from your mobile provider, on which it depends what kind op IP you get. Very often 3G networks are NATted, meaning that you get an IP address from the range 10.0.0.0/8 which cannot be reached from outside.
Using www.whatismyip.com should definitely give you the correct address?
What address did you get when it came back?
How did you verify if this was your iPhone's address? I assume you don't have a firewall installed on your iPhone? Hmm, other thing is your provider is doing some kind of filtering, NAT-ing, or other tomfoolery. If you don't mind me asking, what exactly are you trying to achieve here? Are you trying to run some kind of server-style app on your iPhone? Or do you just want to get a connection between the iPhone and a server - might be easier to initiate the connection from the iPhone side.
You should check if it's at your provider's IP block range - an online whois check should tell you that (www.whois.net).
How did you test whether this was your iPhone's address?
Other option is just to have your iPhone hit a server that you control (using 3G), and check the server logs.
Or just make things easier, and use an app to tell you - e.g. iStat:
http://bjango.com/iphone/istat/
which will give you your cell (3G) IP address as well.

There are two types of IP addresses:
Private IP address (your device IP that you get it from your home Wi-Fi router or from your Teleco provider router to speak to those two routers).
Public IP address (your home Wi-Fi router and/or from your Teleco provider router which they will use it to allow you to speak to another person on the Internet).
**NOTE: Without Public IP address, you cannot speak to people who are on the Internet.
Now both (your home Wi-Fi router or your Teleco Provider router)they have something called DHCP, or Dynamic Host Configuration Protocol. This protocol is used to allocate private IP address to anyone connected to local network (either home Wi-Fi or Teleco provider).
That means both (home Wi-Fi router and Teleco provider router) have one single IP address called Public IP address to allow you to speak to outside world, but first they need to give private IP address to able you to speak with them (your home Wi-Fi router and your Teleco provider router).
If your iOS connected to your home Wi-Fi, then you will have a Private IP address:
1- Go to settings.
2- Click on Wi-Fi.
3- List of Wi-Fi networks will be appeared.
4- Click on your Wi-Fi network name (known as SSID).
5- Click on the blue circle of the exclamation mark on the right side of your Wi-Fi name.
You will see your Private IP Address there very clearly.
Now if your iOS device is not connected to any Wi-Fi network, but it connected to your Teleco provider, then you cannot see your private IP address.
I am sure there is a way to see your Private IP address that you got it from your Teleco Provider DHCP. You have to search from internet or ruin your device by jailbreak it.
For the Public IP Address (no matter if you are connected to your home Wi-Fi or your Teleco Provider), go to your internet browser (e.x. google chrome) and type: "What is my ip address". The result will be between your hand in fractions of seconds!
Now Back to your question:
If you connected two iPhones to your PC and both have hotspot enabled, that means your PC USB ports will handle two IP Private addresses because your iPhones will act as your home Wi-Fi router.
if you have windows OS in your laptop, then go to windows CMD terminal and type:
ipconfig
the CMD prompt terminal will give you number of IP address, there are your two Private IP addresses from your iPhones.
Now if unidentified network message still there, open RUN in your windows OS and type [ ncpa.cpl ], it will take you to network connection setting section, right click on one of your iPhones networks and disable it, keeping the other enabled.
I hope it is crystal clear now.
When the phone is the hotspot for the Telecom cellular provider it actually being used as a Router therefor if you connect laptop to that hotspot you can open network setting on the laptop to view its tcp/ip settings and see the ip of the laptop and the ip of the Router which is the IP of your Phone.
The Ip is a private one, you can ping to it or do what ever you want.
Example of connecting Iphone to Mac Xcode wirelessly:
share personal hotSpot from your phone.
connect your laptop to your phone private network using wifi, search for the ssid you set in your phone and set a correct password.
in Mac go to System prefences->Network->wifi connected->Advanced->Tcp/Ip
copy Router Ip - this is your Iphone private Ip.
In order to connect Xcode to Iphone wirelessly you first need to connect the phone with usb, open window->device and simulators, select your phone and set checkbox "connect via network"
Now if the phone is disconnected from the Mac and the private network is shared as explained, you know the phone Ip, then you can select the phone in Xcode (it remember phones that were connected), open window->device and simulators, select your phone , click on it to get menu of options, select "connect with ip", provide the ip you saw as "Router" previously.
Thats all, hope it'll help somebody.
I'm completely new to the iPhone, so this is a newbie question.
The web development environment I use at work is set up on Windows 7, running Tomcat as a web server. Web Apps are tested by pointing a browser to "localhost".
I've been asked to port a web front end to the iPhone. Since I need to use this same development environment I need to connect the iPhone to the PC via USB or Ethernet.
There is this answer:
"http://stackoverflow.com/questions/3132105/how-do-you-access-a-website-running-on-localhost-from-iphone-browser"
but I was hoping to do it without wireless.
Other questions I've researched are about iPhone development, the SDK, etc. I'm not developing iPhone code, only trying to get the iPhone Safari browser to access the IP address of the local PC, 192.168.xx.xx or whatever.
Seems like it should be simple, a matter of cabling?
it would be an issue of cabling... if the iPhone had an eternet jack :)
But the wifi connection is the only "network jack" the phone has that you can connect to your own network directly with, the 3G or CDMA port gets routed via your mobile phone company, nothing you can do about that. Hence the need for WiFi to access non-routable addresses, like ...
Another option would be to make your server internet-routable, like middapark said. Then you can access it via your mobile phone provider's network and the public internet and can do away with the need to use Wifi.
A third option is to create a VPN tunnel from your iPhone to your local network, again via your mobile phone provider's network and the public internet. But I have no expereince with doing that, so I can not give further advice there.
The problem is most likely because you're trying to get your iPhone to view an internal (i.e.: not internet viewable) network. (Address such as 192.168.0.0, 172.16.0.0 and 10.0.0.0 and are non-routable as far as the internet as a whole is concerned.)
As such, unless you can access your internal network via wifi (or you're prepared to expose the machine in question to the internet, in which case you'll need to use a different IP address) this isn't possible.
The iPhone settings have an IP address for the device when it is connected to a wifi network. Is it possible to get this IP address and establish a connection between a desktop computer (on the same network) and the iPhone?
I want to be able to transfer files between the iPhone and the desktop computer. Some apps like the "Files" and "FourTrack" apps do this.
Can someone please guide me to where I can start?
Thanks a lot for any headsup
Google for SIOCGIFCONF and you'll find a bunch of example code in C for getting all your IP addresses. Once you've enumerated your devices, on iPhone they are always in the following order: Loopback, WiFi, WAN.
Once you have that, you can implement a web server with CocoaHttpServer pretty easily. You'll have to hack it to add directory listings and the like, but it's not too hard. It's not trivial, but it's not too bad.
I think you already answered your question... you have to download an app to do this. I use "Air Sharing" and it works fine.
Is it possible to connect a socket between two mobile devices (iPhones) over the internet?
I am trying to discover the IP of each device and connect directly. I know it can be done with Bonjour but that only works on local networks. I need a high speed connection between two devices over the internet.
Thanks.
If you had both the IP's and they were both routable, it should be possible. I'm not sure though if the IP's given out by the 3G network are routable. If you are using WIFI, the IP you get is almost certainly not routable. Assuming you have a routable IP though, it should be possible.
The trick is just discovering the IP of the other device. The best way to do that would probably be to have each device register its IP with a web service when your app starts up, then query that service to find the IPs of other devices.
It might get a bit tricky managing "unregistering" IPs when the app is closed or when an IP changes though, but it should be doable.
ETA:
If you have a server that they can both connect to, you should be able to implement a solution using that server (i.e. without the phones actually directly connecting to each other). This would avoid the issue of having routable IPs for the phones.
As for how to bridge the sockets together - your server program would basicly work like an old-school phone switchboard operator. You'd have some kind of registration & discovery protocol built into the server software that would allow a phone to register itself with the server, query a list of the other phones currently connected to the server, indicate which phone it wants to talk to, and accept connections from other phones.
Once it knows who wants to talk to whom, your server software would connect the two together by reading from one phone's socket and writing that data to the other phone's socket.
Only a suggestion, but if you can get each of them to connect to a third site, you'll then know the address of each. Send the address of phone A to phone B (and/or phone B to phone A) and then have them connect as you see fit.
Have you looked through all the 3.0 features? Specifically peer networking (the existence of which is public).
WiFi routers often have a feature called "Port Triggering" which allows internal hosts (in this case an iPhone) to inform the router that they would like to have a connections on particular port forwarded to them. I have no idea if the iPhone supports this protocol.
For IP lookup you may consider using DynamicDNS if the two hosts are known ahead of time OR as stated above a custom web service if they are not (i.e. friends exchanging hostnames vs. strangers discovering each other)
This is an old thread, but I just came across it. You could use a STUN server (or NAT-PMP) to get the public IP address/port combo and then SMS it over to the other phone. So long as you open a listening port on the first device, then your second device can just connect directly using the publi IP address/port you sent to it in the SMS (SMS push registry can automatically wake up your app on the second device to do this)
I have run into this issue with an app I was developing. I was trying to connect to a PC cell card from an iPhone. The problem is that AT&T doesn't enable mobile termination for iPhones so it is physically impossible for two phones on an AT&T network to connect to one another. This is straight from an AT&T antenna engineer.
I was able to get this to work by having the iPhone VPN into a server and then connect to the PC cell card but other than that, it wouldn't work.
I have a very strong feeling (but no evidence) that the iPhone address is going to be non-routable. Of course it actually depends on the operator but AT&T give out 10.x.x.x addresses.
Apple have sample (desktop) code that uses Bonjour to implement portmapping on a WiFi router that supports UnPnP.
