Ok, looks good.

Ok, so this works.

No no, all working within it's spec IMHO ;)

dnsmasq is basicaly fine with the hostname, it does not like the domain
you're client is sending.
It tries to protect you from forgery.
If a client would record itself as www.google.com, and dnsmasq would
believe this, it would forward all your LAN machines for www.google.com
to this machine.
Somehow the "domain=localdomain.net" doesn't do the trick.
But when looking again, arnor (and maybe the other machines) is sending
"$HOSTNAME.localdomain" as hostname?
the final ".net" seems to get eaten...
May you can remove all the references to your domain from your
dhclient.conf, for a test.

This should be the hostname only, or?

drop this, dnsmasq should give out the right domain

drop all this fqdn stuff for a test
Which version of dnsmasq is this?

Thats because dnsmasq could not find an entry in it's own db, and thinks
maybe the upstream server know something about it.
To tell dnsmasq that localdomain.net is local, and it should not ask
upstream about it, you may want to add:
local=/localdomain.net/
to your dnsmasq.conf

normally you should be able to put 0.0.0.0 in here, so dnsmasq will
automatically fill in the right value for your interface
