Confused about Cell Phone Carriers IPv4 / IPv6 & SmartSdr IOS

I'm looking to change Cell Phone carrier. Looking at older post doesn't seem to address most of the carriers going to IPv6. In a 2 year old post Ria & Tim talk about Flex may move to IPv6. Marcus mentions T-Mobile IPv6 will not work with IOS. T-mobile is the carrier that I'm thinking of moving to. Does SmartSdr v 2.1.33 support IPv6 ? If not, when is it expected. Moving from Android to I-Phone / I-Pad will cost a little more but worth while if I know it will work...Also, will Marcus have to re-write IOS to work with IPv6 ?

I've had no trouble using T-Mobile with SmartSDR iOS. My shack ISP does not support IPv6 so there is translation to IPv4 going on somewhere, but based on my experience I would not expect you to have any difficulty using SmartSDR IOS over the T-Mobile network.  I've tested it with the "use IPv6" switch set both to "on" and "off" in SmartSDR iOS and both settings work. 

I'd be happy to try connecting to your setup via SmartSDR iOS on T-Mobile / iOS to confirm that it works.  If that would be helpful just contact me at matt@nq6n.com.

Thanks Matt..  But how do I know if in my area that T-mobile has IPv6 or IPv4..  As I mentioned Marcus said IPv6 would Not work with IOS.. I have even tried to get answers at a local T-mobile store..  knowing I'd prob not get an answer... I need something firm before I plop down some bucks... And I'm  still very curious if my Flex is able to use IPv6....  I may still may contact you about you trying access.... I'm going to waste some more time calling T-Mobile about what IPV they use...  Grrrr..    Thanks again..

Alan,

Ahh. I know my T-Mobile uses IPv6 because when I connect to the personal "hot spot" my computer gets assigned a public IPv6 address. You might be able to test this at the local T-Mobile store just by loading a website like http://ipv6-test.com/ in the browser of one of the demo phones. 

I too am curious to know if the Flex will work directly with IPv6!

Still again ...  Do the different units ( I-pad, I-phone, hotspot use) use different protocols ? If I buy I-Pad with data plan... Which protocol do I get ??  LOL...  OH,,,  I may run over to the T-Mobile store & try that site you listed....

My AT&T iPad and iPhone operate on BOTH IPv4 AND IPv6 But my Spectrum Cable Internet only supports IPv4

I am a T-Mobile user.  When they changed their network protocol to IPv6 only, SmartSDR for IOS quit working.  However when Apple pushed IOS v 11.2.5 to my iPhone 7 plus, and after conferring with Marcus, he added a IPv6 option  to SmartSDR for iOS V 2.3.0, The app works flawlessly.

Ria... When I went surfing for info on the Lightning Adapter that comes with the I-phone, Only Audio Out is mentioned...  No Mic input . At the Antlion Modmic5 site it shows a Y-conn with 4 cond plug...  that looks like it has line for mic & stereo L & R + gnd. Did you buy a after market Lightning adapter that has extra cond for mic ??

The lightning adapter most certainly does audio in. 

The modmic 5 I use with a set of bose QC25s because I wanted a boom mic. I used a splitter and a small cord to go to the headphone. I should really take some pics.

Thanks again Ria...  Even calling a cpl of T-Mobile stores, they didn't know..... OH...  I forgot to ask...  Having a choice of Different I-phones... ( 7, 8, 8+ ) & memory..  Is one considered a minimum usable Or best one to buy ? Don't know which can run 2 apps at once, like IOS & another to remote shut down the radio  or rotate antenna...

Get the latest you can budget for. I have an iPhone X but the latest SmartSDR needs a minimum of iOS 10. I would get an iPhone 8 or X if you could. It runs really smooth on my iPhone X. But it runs fine on my iPhone 7 as well.

Sorry, I forgot to mention that T-Mobile has always and still continues to support IPv4 apps such as SmartSDR for iOS when using your iPhone as a Personal Hotspot for tablets as well as any wifi device running SmartSDR software.

SmartSDR for Windows, Maestro and all FLEX-6000 are designed to work with IPv4 only.  You cannot connect to the radio on your local LAN using IPv6.

Agreed, however there is still the issue of IPv6 only mobile carriers and SmartLink. SmartSDR for iOS fixes this by having IPv6 capability.

I suppose there is no need at present for SmartSDR  to have IPv6... That  2 year old post where you & Tim talked about IPv6 got me wondering...

I don't think he precluded the need, just stated that it's not there right now which is correct. Whether it will be there in the future is unknown. If you read that thread, you will see Tim mention the 80/20 rule that they use to apply to enhancements and features. 

iOS did need to have it because Apple requires IPv6 compatibility now and wireless carriers are using IPv6 and doing 6 to 4 translation.
