I'm bored today, and found that a majority of the 10.x.x.x subnet is pingable. I thought that these were supposed to be private ips? I'm pretty sure these ips are from distinct computers, since the pings vary quite a bit.

Can anyone explain?

BTW, I'm on comcast. Maybe this is a way for inter-comcast communication?

Yes, i know. You see, that's the reason why I'm asking you guys why a majority of these are pingable.

Some moron has something set up VERY wrong. (Or you're on a 10.x.x.x LAN and don't know it. Or VPN'd or otherwise tunneled to a 10.x.x.x LAN)

For example, doing a fping gives me:

c32 dhe # fping -g 10.69.1.1/24
10.69.1.1 is alive
10.69.1.2 is alive
10.69.1.3 is alive
10.69.1.4 is alive
10.69.1.5 is alive
10.69.1.6 is alive
10.69.1.7 is alive
10.69.1.8 is alive
10.69.1.9 is alive
10.69.1.10 is alive

10.69.1.32 is alive
10.69.1.33 is alive
10.69.1.34 is alive
... and so on

However, note that not every ip is taken though.

Why does everyone think that being able to ping or not ping is the be all, end all of network connectivity? ;)

Do a tracert to the IP address and tell me what you see...

You're tunneled into something. Probably a DDoS botnet set up by some virus/spyware on your machine.

Tracert should show no hops, since the 10.x.y.z subnet shouldn't exist in any routing tables.

Try grabbing banners from some of these machines.

That's not the first hop. The first hop is my ip, which i took off so you guys won't hack me, especially if i'm vernable at the moment :p

My computer is directly connected to a router, which directly connects to the cable modem. I doubt the router and cable modem are the problems; it's pretty hard to hack one of those thigns, right?

But i'm having these problems on all of my computers.

I do have a private DNS server on a computer, but I doubt that has anything to do with ip addreses, does it?
