My phone's IPv4 address is 192.0.0.4, which is used for 464XLAT. Mine is 10.190.*.*, after disabling the WiFi.
Plays havoc when I have to tether my laptop and use gmail with it - google thinks I suddenly moved 800Km north or 300 west abd blocks my account.
Yet another reason to move to IPv6. I hadn't heard of that one before.
Again, that is not up to me. I don't make that decision. My phone uses what the ISP provides... I don't have a choice in what they do or not. If you google, you will find out that many ISPs do the same: give phones an address in the 10.*.*.* range and use NAT. I can be thankful that my ISP doesn't do it on the home fibre network - because some do. Here, see: <https://en.wikipedia.org/wiki/Carrier-grade_NAT> Carrier-grade NAT (CGN), also known as large-scale NAT (LSN), is an approach to IPv4 network design in which end sites, in particular residential networks, are configured with private network addresses that are translated to public IPv4 addresses by middlebox network address translator devices embedded in the network operator's network, permitting the sharing of small pools of public addresses among many end sites. This shifts the NAT function and configuration thereof from the customer premises to the Internet service provider network. Carrier-grade NAT has been proposed as an approach for mitigating IPv4 address exhaustion.[1] One use scenario of CGN has been labeled as NAT444,[2] because some customer connections to Internet services on the public Internet would pass through three different IPv4 addressing domains: the customer's own private network, the carrier's private network and the public Internet. Another CGN scenario is Dual-Stack Lite, in which the carrier's network uses IPv6 and thus only two IPv4 addressing domains are needed. -- Cheers / Saludos, Carlos E. R.
