you are so over your head, you have no idea what you are talking about. Phones don't need public dot quads.... at all. On Tue, Dec 16, 2014 at 10:06:45PM -0500, James Knott wrote:

(1) There are simply not enough IP addresses. (2) There are already more mobile devices than there are IPv4 addresses.
Since those mobile devices are all on line, along with all the computers already on the net, (for some imprecise values of "all") it can easily be deduced that there ARE enough IPV4 addresses.
Let's put this into perspective. At the moment, cell phones generally do not use VoIP, unless the user adds some VoIP service. With 4G, all phones will be VoIP. With NAT, as currently used, you need a "gateway" server, including STUN to move all those connections between the RFC 1918 addresses used by the phones and the rest of the Internnet and again at the other end to get back to the desitation device. This has to be done for the duration of the call, adding latency and cost. If the devices had public addresses, then this stuff wouldn't be necessary. With the way SIP/RTP is designed, it should only be necessary for the phones to connect to their "server" to set up the call, after which it drops out, with the phones communicating directly in peer to peer operation. However, NAT kills this, forcing the use of gateways, STUN and more garbage that wouldn't be necessary if there were sufficient addresses. However, this is just the beginning. Another thing that's coming is the "Internet of Things" (IoT), where there will be several devices in your, car, on your person and elsewhere, all requiring IP address. So, if you want to reach the IoT devices in your home, from elsewhere, they will need their own public IP addresses, free of that load of crap called "NAT". The existing situation, of more mobile devices than IPv4 addresses, on top of all the existing wired devices that can't get addresses is just the being of the problem that will only be magnified when IoT really kicks in. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
