    HI, i hope this is the correct section.

    I have one toshiba laptop wich has internet protocol tcp/ip
    and a compaq laptop that has internet protocol version 4 tcp/ip

    I can't ping eachother ip for some reason. i tested with a different comp wich had the internet protocol tcp/ip and they ping eachother succesfully but not with the version 4.

    is it possible to connect the version 4 with the basic one? or do i have to configure something.


    p.s. the ethernet are conected to a wireless router.

    Unfortunately, they're not the same thing if one of the systems is running _Vista. For who-knows-what-reason, MS decided to call its implementation of IP version 6 just plain "IP" in _Vista, and the old standard version of IP, IP version 4, "IPv4."

    IPv4 and IPv6 are not the same thing, although IPv6 can essentially be piggy-backed through IPv4 (I don't recall the substance of the implementation - I read it somewhere in one of the innumerable technet articles I wade through to satisfy my masochistic tendencies :D ).

    Basically, to fix the problem, the OP is going to have to get all of his computers on IPv4 or IPv6 in order to get them to talk to each other. I'd surf on over to the microsoft website and do a quick search on IPv6 to see what comes up (or check in the help function on the computer in question).

    Vista uses IPv4 , thats why i say its the same thing as the normal IP in XP. Because I can connect to other XP computers fine with IPv4

    IPv6 is the new upcoming protocol when IPv4 addresses run out. They should have implemented this a long time ago

    You would normally need a "bridge" to translate from one protocol to another.

    IPV4 and IPV6 are both supported in XP and Vista; however, it must be enabled in XP. Just go to the properties on your NIC in the Vista machine and check which protocol is being used. Make sure IPV4 is enabled and IPV6 is disabled.
