Unknown network activity on iPhone 6

Hello all,
I have found a network "peculiarities" with my iphone 6.
I have a number of devices connected to my Netgear WNDR 4300. I was debugging some weird LAN-activity, and came across that my recently bought iPhone 6 registers 3 network addresses on my router (screenshot attached)
My wifi is only giving out 192.168.1.* addresses, however the iPhone is using a 10.0.0.* address and a high 192.168.*.* address. You can see from the screenshot that the same MAC address is common. When connecting any other device, like the iPad Air 2, this does not happen. Its important to notice that my DHCP-server on the wifi-router does NOT give out 10.0.0.* addresses, on any interface, on any band. Guest network is disabled.
When disconnecting the iPhone 6, the addresses unregister themselves from the DHCP.
Does anyone have any information on this ?
Regards

I have almost the SAME exact situation here. I stumbled across this when looking at the router connections after my wife bought her new iPhone 6. I like to reserve addresses for devices so that we can use the routers restrictions to prevent access during nighttime hours for the young ones. When my wife's phone is connected, we have two devices showing for her phone. One is the phone itself, and one just shows up as a network device. Unique MAC address receiving an IP from the router. I have looked and looked all over the net and on the phone, but can't find the answer. I just found your post today, but see no one has replied with an answer .
Odd thing with us is, that the unknown device is named with my wife's oldest daughters name who is away at college. I know this daughter used my wife's macbook to connect her iphone to itunes several months ago, and it's almost like this has gotten attached to my wife's profile somehow. This never happened until the 6, and I'm geeky enough to not let it go as I HAVE to know what's causing the second connection. Like you, turn the phone off, both IP addresses go away....turn it back on, they reappear.

Unknown Network Activity Originating From Mac Mini

Hi All,
I checked my firewall logs this morning after connecting the mac, and made a worrying discovery: it appears that my MAC is trying to authenticate against some services that I don't recall setting up.
Here is the log:

These are all items that I don't recognize. I have my mini set up with a mobil account, but I have a different IP set up in VPN for that to use. And once I have VPN activated, I use a local network account from my XServe that is running OpenDirectory to take care of all the authentication, etc.
The only items I have listed for automatic startup are:
- MCXMenuExtraTool
- Skype
- SpeechSynthesisServer
- iTunesHelper
From what I can tell, only Skype has been added by me.
Any ideas?
Thanks,
Mike Bronner

Well, let's see. NTP is the network time protocol, which keeps the system clock set to the correct time by checking with a server that is synchronized with a reference clock (in this case, it's checking with the NTP server at Apple that's sychronized with an atomic clock at the National Institute of Standards and Technology).
Then there's a bunch of traffic to OpenDNS.org (208.67.219.132) -- probably your machine checking to see if it has permission to update the DNS server with your machine's username and password (which it doesn't have permission to do).
The remainder look to be home broadband accounts -- probably pings from infected home computers looking for a mate. It's surprising that your router/gateway lets that sort of thing through. Do you have all the traffic forwarded to your Mac without any filter? Is there no gateway between the machine and your ISP?

Extended network activation? iphone 5? in college no verizon service

in morgantown wv, there is many Verizon cell service. I just got my iphone 5 tried activated and doing so my iPhone 4 got deactivated now I'm without a phone. any tricks?

Hello 2020word!
I know you're eagerly awaiting to use your new iPhone 5! When activating a 4G LTE phone you will actually need to be in direct Verizon Wireless coverage.
You can use this map: http://bit.ly/ymXLCI to find the closest direct coverage to you. Once you have it activated you will be able to bring it back to school and use it though you may have limited data capabilities.
Let us know if you have any other questions!

Thank you for your response. However, I have done that plenty of times and each time I try to restore my phone, it extracts the software and then when it says restoring with the loading bar, an error message comes up saying an unknown error has occurred.

Customer Enhancement in Project Network Activity

Hi Gurus,
I add a new subscreen in project network activity(cj20n). I use the structure CI_AFVU as field structure.
It contains two fields 1) CI_AFVU-ZZSALES_DOC
2) CI_AFVU-ZZSALES_ITEM.
The exit is CNEX0008 in which I have two function exit for PBO and PAI for that subscreen.
EXIT_SAPLCONW_002 for PBO
and EXIT_SAPLCONW_003 for PAI.
My problem is in PAI I am not able to import data from screen. I use the following code:
CNCI_AFVU_EXP-zzSALES_DOC = CI_AFVU-zzsales_doc.
CNCI_AFVU_EXP-zzSALES_ITEM = CI_AFVU-zzsales_item.
and one more thing is that Different Activity takes the same Value in both the customer fields which should be different. Although in debugging mode CI_AFVU display the values, but when I am trying the above code it give me a compile time error 'Field "CI_AFVU-ZZSALES_DOC" is unknown. It is neither in one of thespecified tables nor defined by a "DATA" statement . . . . . . . . . .'
I need a solution for that, Pls help.
Thanks,

*. But we can find where the cost element is. It seems the field disappear.
PLease help.
Thank you.
Nies

Hi,
Yes. It is already blank. But the cost element field still not appears when we create activity service. It shows :
Please specify a valid account assignment
Message no. SE181
Diagnosis
You have entered an account assignment category in the document item for which an account assignment is mandatory.
All account assignment lines in the service specifications either have been deleted or are inactive (e.g. account assignment lines of a contingency item).
Procedure
Please enter an account assignment for the services or value limits.
The entry of an account assignment is unnecessary if you choose "unknown account assignment" in the document item.

I just made my account and when I try to log in it tells me "unknown network error" what do I do?

13017 Received TACACS+ packet from unknown Network Device or AAA Client

I am adding new routers to our Corporate network for a new MPLS network. I am getting 13017 Received TACACS+ packet from unknown Network Device or AAA Client errors for these new routers. They are added to ACS 5.4.0.30 correctly just like all of our other devices. We have never had real routers on the network before, just switches and access points. Is there something special I need to set in ACS for these to work and authenticate correctly? I can only access the currently with built in login locally.

Network activity icon turns when making a phone call

Not sure if this is normal or not, but when i make a phone call the network activity icon scrolls for a few seconds. this icon is the one to the right of the 3g letters at the top of the screen. Is this normal? I'm used to seeing this move when checking email or surfing the net but never when just making a call.

I had the same problem just one hour ago. I could not hear the person I's talking to unless I put it on speaker.
I restarted my iPhone 4 and still the problem was there.
And it automatically started working again in one hour.
I would suggest to shake the iPhone a little and try to reboot and see if it's helping.

Nombre de dispositivo "Unknown" en Buscar mi Iphone

Porqué me aparece como nombre de dispositivo de una imac "UNKNOWN" en buscar mi iphone???. Ya eliminé otra imac que tenía mi nombre y además desactivé buscar mi iphone en el equipo viejo; sin embargo me sigue apareciendo para la imac nueva "UNKNOWN"..........ayudaaaaaa

Hola. Para desactivar buscar mi iPhone es imprescindible introducir el ID de Apple y la contraseña con las que se activó el iPhone. Esto es una medida de seguridad para evitar que un iPhone sea robado y usado por alguien que no sea su dueño.
Sí desconoces estos detalles no puedes desactivar buscar mi iPhone.
Llama a Apple Care y trata de convencerles que tu eres el dueño del iPhone, porque no hay ninguna manera de saltarse esta medida de seguridad.

Trouble activating Sprint iPhone 4s on Sprint

I'm running into some problems activating an iPhone 4s on Sprint, after it had been on FreedomPop for a couple of months. First, some background:
I have an iPhone 4s, purchased from Sprint, that was on my account for a little over 2 years before it was upgraded. Once upgraded, it sat in a drawer for a couple on months until a friend needed a new phone. About that time FreedomPop (a Sprint MVNO) allowed certain Sprint devices to be activated on their network, no Jailbreaking or unlocking required, just give them the ESN and if it were a supported device, they'd activate it. The iPhone 4S was on the list, so we gave it a try. It lasted maybe 2 billing cycles on FreedomPop. Last Wednesday service on FreedomPop was cancelled because the actual usability of the service was, well, crap.
Now that Sprint allows BYOD w/ no credit check accounts on to be added to a Framily ID, we tried to go that route with the iPhone. We called Wednesday morning to deactivate the FreedomPop account and a couple of hours later tried to activate it on Sprint. No dice. They said that the ESN was coming back as "incompatible." I assumed this might mean that FreedomPop has not actually let the device go, and I may need to wait a business day or 2. No problem. I activated an old LG phone I also had so that my friend at least had a working phone with which to make phone calls and send texts.
Fast forward to Saturday, I do a full reset on the phone, the "Your phone is not activated" message comes up on the lock screen, the Network shows "Unavailable" in General/About so I assumed this means we are free and clear. I even swapped out the SIM card (obtained from Apple that weekend), just in case. I tried to replace the LG phone with the iPhone on the website. I entered the ESN and it said that it was invalid. I tried again, thinking I'd fat fingered it, and same result. I then tried entering the IMEI, and same result. At this point it said I had tried too many times and it directed me to a chat agent. I explained the situation to the agent and s/he tried to activate it and was unable. S/he directed me to call telesales, where I spent 35+ minutes on the line with an agent who was also unable to activate the phone. He made notes and was supposed to escalate to another group for research, after which he'd give me a call with their findings. He said I should hear from him by yesterday, but I didn't.
So, ultimately, has anyone ever seen anything like this? I need to stress that the phone is NOT unlocked, NOT Jailbroken, NOT hacked in ANY WAY. It is 100% completely stock, purchased from a Sprint store.
Anyone have any ideas on what could be wrong, and how this could be remedied?

Anyone here would be guessing, but probably the MEID (you DID say Sprint, which is a CDMA carrier and thus has MEIDs instead of IMEIs) is still registered to FreedomPop in Sprint's database. You need to get Sprint to work it out, or wait a few more days. From what I have heard about FreedomPop I'm not surprised that they can't get this right.

TS4020 How can I locate my lost iPhone 5 with find my iPhone app ? Plus someone tried accessing my apple I'd on FaceTime on an unknown number related to iPhone 5 is this who's got my phone and can I track a number ?

How can I locate my lost iPhone 5 with find my iPhone app ? Plus someone tried accessing my apple I'd on FaceTime on an unknown number related to iPhone 5 is this who's got my phone and can I track a number ?

If you activated the Find My iPhone service (in Settings>icloud), and if the device's batteries still have a charge, the device is not turned off and has not been reset and is connected to wifi, then you can try to track it. Using a computer's browser, log into icloud.com and look at the Find My iPhone page. On a device, invoke the Find My iPhone app (get it for free at the itunes app store) and log into the icloud account. Note: The Find My iPhone **app** does not turn on the service, you can only do that through Settings>icloud.
If the device is listed as "offline", then one of the requirements listed above is not met (like being connected to wifi, or if the device was stolen and the thief reset it).
