    Anyone know what "Tunnel Adapters" are in ipconfig?

    Hello.

    New Vista machine. I do "ipconfig/all. I see the following:

    1. Windows IP configuration section. That's fine.

    2. Wireless LAN adapter Connection Information section. That's fine.
    It shows the way I am connected, and it all makes sense.

    3. Ethernet adapter Local Area Connection. That media shows as
    disconnected (which it is) so that is fine.

    Now we get into the weird stuff.

    4. Tunnel Adapter Local Area Connection* 6
    Media State: Disconnected.
    Connection-Specific DNS suffix: <empty>
    Description: Isatap.{Long Hex Number inside curly brackets}
    Physical Address: 00-00-00-00-00-00-00-E0
    DHCP Enabled: No
    Autoconfiguration Enabled: Yes

    5. Tunnel Adapter Local Area Connection* 7
    Connection-Specific DNS Suffix: <my ISP>
    Description: isatap.<my ISP>
    Physical Address: 00-00-00-00-00-00-00-E0
    DHCP Enabled: No
    Autoconfiguration Enabled: Yes
    Link-local IPV6 Address: fe80::5efe:<assigned-IP-address>%11(Preferred)
    Default Gateway: <Empty>
    DNS Servers: <Dns Servers provided by my ISP>
    NetBIOS over TCPIP: Disabled

    6. Tunnel Adapter Local Area Connection* 9
    Connection-Specific DNS Suffix: <Empty>
    Description: Teredo Tunneling Pseudo-Interface
    Physical Address: 02-00-54-55-4E-01
    DHCP Enabled: No
    Autoconfiguration Enabled: Yes
    Link-local IPV6 Address: fe80::14f6:<4-more-hex-quadruplets>%12(Preferred)
    Default Gateway: <Empty>
    NetBIOS over TCPIP: Disabled

    Can someone explain to me what 4, 5, and 6 are? Many thanks.

    Tunneling is how you do secure (encrypted) communications across an
    untrusted network (the Internet). Those look like
    IPv6 tunneling. See these pages:

    or search for "Vista Teredo Tunneling" or something like that at MS or
    Google.
