+Allow pppd to operate without having an IP address for the peer. This
+option is only available under Linux. Normally, pppd will request the
+peer's IP address, and if the peer does not supply it, pppd will use
+an arbitrary address in the 10.x.x.x subnet.
+With this option, if the peer does
+not supply its IP address, pppd will not ask the peer for it, and will
+not set the destination address of the ppp interface. In this
+situation, the ppp interface can be used for routing by creating
+device routes, but the peer itself cannot be addressed directly for IP
+traffic.
