Dear NETBSD guru ;-)

when looking at the output of netstat -i
I do see something like this:

Name  Mtu   Network     Address              Ipkts Ierrs    Opkts Oerrs  Coll
le0   1500  <Link>      8.0.9.15.65.54       78186     0    97958     0  1210
le0   1500  134.2.170   centauri.tat.phys    78186     0    97958     0  1210
.
.
.


What I would like to know (any pointers to documentaion) is:

What is special about 8.0.9.15.65.54?

Why are there two entries for the single ethernet device?

Is there done any copying inside the kernel?

Where may I optain technical information about the *BSD kernels and 
networking?

 Yours,
