Yes. It is a bug. I has been fixed already and recent snapshots does not
send that extra data. For example:
By the way: if you are after static reservation, you might also consider
adding following line to the client.conf:
It will instruct dibbler client to generate DUID based on the link layer
address only and don't add timestamp. That will make duid predictable. For
default DUID type (link local+timestamp) you don't know client's DUID
until it is started for the first time.
It will only affect DUID creation procedure. If the client has DUID
generated already, it will be ignored completely.
Hope that helps,
