Hi Stefan,

I'm sorry if my question would be too stupid or shallow, I just want
to make sure because I'm really new to this.

I have run an example from [1] on client-server model using UDP and
IPv6. To run this example, on the client side I run the command:

"listener <IPv6 of another machine for lowpan interface>%lowpan0
the-payload-is-here"

According to [2], <IPv6 address>%<interface's name> notation means the
machine will try to communicate  to <IPv6 address> machine through the
<interface's name> interface. Hence, I basically have run
client/server program with Linux IPv6 over the lowpan0 interface.
Alexander Aring gave me a good presentation slide [3] and on page 12
it is clearly written that Linux still uses AF_INET6 for 6LoWPAN.

I just want to make sure whether my approach on making client-server
model over 6LoWPAN is right. I am not sure because I don't know
whether the IPv6 header is compressed using 6LoWPAN adaptation layer.
