Yes. Smartphones have one or more IPs, which may or may not be IPv4/IPv6 & public or rfc1918 address space. There is some tunnelling between the radio and the packet core, but they typically are first class Internet nodes. You could look at them as analogous to cable modems or wifi clients. Feature phones (eg. Motorola Razr) might be using a proxy gateway to to internetish stuff and that gateway actually owns the IP address they use similar to a campus network with a web proxy gateway. Older crackberries tunnel all their traffic inside udp-like encrypted datagrams back to the RIM data centers where they emerge onto the Internet like AOL dial-up subscribers of yesteryear. LTE is IP end-to-end; 3G is IP to a radio-wire interface. ________________________________________ From: Larry Sheldon [LarrySheldon@cox.net] Sent: Wednesday, August 14, 2013 6:50 PM To: nanog@nanog.org Subject: Re: How big is the Internet?

The NSA will need some more hard drives. lol

Do "we" (meaning y'all) even know the edges look like? My elderly crackberry does internetish stuff like email and browsing and file transfers when there is no wiffy in sight. So it either speaks TCP/IP with the towers (it might, I have no clue), or there is non-TCP/IP fabric in the skirts. -- Requiescas in pace o email Two identifying characteristics of System Administrators: Ex turpi causa non oritur actio Infallibility, and the ability to learn from their mistakes.
