the # of microsoft isatap adapter growing, from #0 to #8

    Question

  • as the title motioned, i found in my win7 ultimate 32bit Device Manager, there are 8 microsoft isatap adapters shown.

    i have never have an ipv6 network if i have not forgotten. why these adapters growth?

    i see it won't have any disadvantage, and i just want to know how this occurs and if i could clear some duplicated entries.

    i think the # will grow in future.

     

     

    i type the ipconfig command, it shows as follow,

  • You don't have eight isatap adapters. you are only showing three. The others are for your wired and wireless adapter and virtual adapters for your VMware stack.

    isatap runs IPv6 over an IPv4 network.

    If you are not using IPv6, then disable it on your network adapter(s).
