Did you get Pinged?

Didn't know this was possible, but a guy pinged every open modem, I phone, and Android device on August 2 to get a snapshot of the internet. Yes, there are flaws in the true picture (time zones, business hrs. in various countries, etc.) ;however, it is interesting.

You're right that most smart phones aren't pingable on the open Internet, but that isn't because they don't have IP addresses, it's that they have private IP addressing that is "hidden" behind a public IP address. If you'll allow a silly analogy: think of public IP addresses (also called registered or routeable addresses) as the front door of a house. Think of private addresses as all of the internal doors inside a house--bathroom doors, bedroom doors, and so on. You can knock on the front door anytime you'd like, but unless you're invited in or you're breaking & entering, you cannot knock on (ping) the internal doors. The device that has the registered address (your DSL/cable "modem&quot performs something called Network Address Translation (NAT) so that your phone, 2 pc's, and 3 tablets and all get out to the Internet. There's just a single registered IP address, and it lives on the DSL modem. When your PC and tablet are both trying to get out to the Internet, your DSL modem does the NAT translation and both of your devices are seen as the same IP address out on the Internet. The actual, private IP address on the device itself is never seen on the Internet. ISP's are configured to crush these addresses if and when they see IP's in the format 10.x.x.x., 172.16.x.x, or 192.168.x.x. Those addresses must be network-address-translated (NATted) to an outside/registered/routeable address. NAT can kind of sort of be thought of as mailing a letter to a large company in a 60-stroy building. The post office carries the mail to the main mailroom, and someone else (the dsl modem, in our example) delivers that mail internally to whatever floor/desk/cube it goes to. It's not a perfect analogy, but hopefully it gets the idea across.

like I do (never turning it off), you can get pinged is what the article says the guy did. The ones turned off - and I suppose there were many - didn't get pinged.

But there's pinging and THERE'S PINGING---

I see one lonely ping in central Greenland, probably the Navy installation there.

When we get into our discussion of network communications, I explain a certain software's PING command as sending a single ping -- "One ping only, please", in the faintest Scottish/Russian accent. There are usually one or two students who look up and grin!

Along with basically everything else I don't explicitly use myself. So I suppose I got pinged, but he would have gotten no reply.
