Any of those addresses are fake ones from either pppd or the modem
because of some internal error or miscommunication.  I don't think
anybody has figured out yet why.  In any case, NM 0.7.2 and recent NM
0.8 snapshots should detect those address and substitute known-good
servers for them (4.2.2.1 and 4.2.2.2).  Not optimal, but at least you
can get online.

I see this occasionally with T-Mobile US and my Huawei stick, but I've
never seen it with Option devices for example.
