What the @#@$@ is Tunnel adapter Teredo Tunneling Pseudo-Interface??

This is what I get when I run IPCONFIG. It gives a strange IP address and includes sonething called "Tunnel adapter Teredo Tunneling Pseudo-Interface:" Does anyone know what this is? Should I get rid of it? How to get rid of it? Before I reformatted my drive this wasn't there. I have 2 comps connected thru a DLINK router and I can ping everything fine from SYSTEM1 but I can't ping from SYSTEM2 to SYSTEM1.

Any help will be greatly appreciated

right click My Network Places, properties, Local Area Connection, properties, look for IPv6 protocol or something similar.

A typical list would look like:
client for ms networks
file and print sharing for ms networks
qos packet scheduler
Internet Protocol (TCP/IP)

Do you see the "Tunnel adapter"?
if so you can remove it.

I apologize for piggybacking onto this ... but what if that information isn't listed in the card? What if you uncheck ipv4, reboot and its still there?
What information do you mean? The IP address information? What is still there after you uncheck ipv4?
Are you talking about IPv6?

Unchecking something does not unistall it, it just disables it from working.
It's a registry edit + unchecking TCP/IPv6 in adapter properties, that will disable IPv6 on everything but loopback.  But why?  Leave it on and transition... Teredo and 6to4 are great!
pfiddy_twintek - If you're going to disable IPv4 you might as well not have a computer!
