    PPP Running with IPv6 support or not means nothing if those addresses
    appear or not, it is because your kernel is compiled with IPv6 support, so
    the link local addresses as you see will appear, also, if you want to try
    to remove them, you will most likely need to put -inet6 on the command
    line, although i don't believe it is possible to remove link local
    addresses... ie - disable it in your kernel and it will disappear (you
    might also want to disable it for world programs too as someone has
    stated in case of any problems...)
