What's up with this... The DOD wants to know what i'm doing?

I searched my ip geolocation on my phone ##debug#, Data Status, and it says
Technology: CDMA- EvDo rev A
IP: 21.80.73.xx
Last Error Code: 0

Well that IP takes me to the location here? Anyone know why this is? Other ip addys are accurate as to what they are on this site and others. Now I'm curious lol.

No Sprint like many Wireless phone companies use NAT, to translate a public IP into a private IP (Just like your NAT router a home), they have so many devices and not enough IP's so they use ranges that are not found on the internet and never will be, this is one of them.

Oh, that makes sense. Smartphones kind of make me nervous anyways. Not that I do anything wrong, I just value my privacy and dont want big brother in my pocket also. I see why that would work that way and didn't even think about it.

They also do this on their Virgin Mobile service. Best guess so far is that since sprint does/used to do a giant chunk of the dod networking they are re-using "dark" (legitimate but unused ip addresses) internally.

Are you really getting that assigned on a sprint branded product?

Or are you on Boost or Virgin Mobile?

I've never had a Sprint device that didn't have a routable IP. You can even pay $5/mo for a static IP.

Maybee they are finally using those IP's as their real IP addresses?

Does your internal IP match your external IP?

on the phone dialer you can usually dial:
*#*#4636#*#*
then choose Phone Information
then down below the ====DATA==== line it will list your local address

If you compare that to the address you get when using the browser aimed at »whatismyipaddress.com/ do they match?

That is how they do they Virgin Mobile... they assign a dark ip as the internal network, then proxy to one of their normal sprint ips as the external... the last octet usually matches as well (internal x.y.z.23, external a.b.c.23).

Perhaps they are switching sprint handsets to this setup? Maybee it's just a goof up?

On a handset you won't notice much... the proxy setup only really hurts when you are running a service (like remote desktop, or a network camera etc) as they never pass the external requests through to the internal address unless it requested it.

Now if they start doing this to sprint data cards... well that would be a serious problem for those who are used to being assigned a proper IP!

Thanks for the info!
