[lug] talking to a 10.x.x.x box

[McIllece]

I have a question about connecting to a friend's stand-alone machine.

He's been using Linux for about a year and recently got DSL through Qwest.  
Qwest provided a Cisco 678 router and a Qwest technician configured it (set the 
password) after fixing some problem with the DSL line.

After my friend got on the internet using his new DSL line, I asked him what his 
current IP address was.  He did a /sbin/ifconfig and sent me the eth0 entry for 
his ethernet adaptor and it showed an inet address of 10.0.0.2.

I've never seen a machine with a 10.x.x.x address.  I do know that www.arin.net 
says "These blocks are reserved for special purposes" and that I can't even ping 
that address.  I'm lost as to why he doesn't have a normal IP address or how I 
might be able to connect to his machine.

Might anyone know?

TIA,
Matt
