mmm troublesome
cose here i have trouble with electric power
if i hav a black out all the ipv6 computers can get off on the network if
the domain pdc server get broken as the mail+-router server both debian
with ipv4 and ipv6 support
i was thinking install radvd in the debian box runing as router .
but now i just think :/
if can be troublesome migrate my lan to ipv6 or only leave ipv6 computer
the servers only and a few unix computers on my network

yes but for example
the computer 10.30.1.3
have ipv6 support can view an ipv6 computer using ping6 right?

how did u do that ? gateway6: ????
