Thanks to johnpoz & phil.davis.
Sorry i apparently either did not receive a reply or missed them in my e-mail
I guess my problem was that I've always thought of the (.***) as the extension and not the domain.
and wouldn't you know it, as long as you don't put any (_) in the domain fields it's all fine and dandy. :) :D ;D :o ??? ::) :-[ :'(
so using (hotspot) as the host, and (.m2m) as the domain, it's all of a sudden accepted as a correct and valid response….... & YEAH it Works! (in both the host and domain override boxes).
oh and no (WWW.) required, the app simply does not require that.
so now I can grab my iPad and manage my hotspot, which manages my WAN Internet connection. which is very handy for details like current DATA usage!!!, session usage, text messages, battery state, attached devices ( which should only be my PFS Box (Have To Make Sure the Neighbors Don't Get on as Somebody Else Is Slightly Paranoid, And I'm Happy with WPA2 Passwords), And Other Miscellaneous Settings.
But Best Of All, i can let other people in the house use the app to see how much data we've used so far without using the data. ( of course accessing the hotspot may not always be accurate, but is at least local and a relatively close estimate of usage)
