Question : 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

IPv6!!?

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.
