Hello,

I have a newly installer FC6 on x86_64, and when I run
ifconfig -a I get at the bottom
...
...

sit0      Link encap:IPv6-in-IPv4
         NOARP  MTU:1480  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

					
I have two questions regarding this:
can I get rid of this sit0, so that in next boot it will not
appear when I run "ifconfig -a" ? I don't use ipv6 (and will not
use it until at least FC7 , but probably also not after FC7 is out).
And I don't use ppp/slip on this machine (nor any special
net features).

Second: when I run "lsmod" I see : "ipv6" ; can I get rid of this module
so that in next boot it will not appear ? (As said, I will **not** use
ipv6 in the near future).

Regards,
Ian
