Ok, here you are:

1) $ cat /etc/resolv.conf
nameserver 192.168.1.1


2) $ dig furdishcamp.com

3) $ host furdishcamp.com
Host furdishcamp.com not found: 3(NXDOMAIN)


When I do ping I get:
$ ping furdishcamp.com
PING furdishcamp.my.domain.here (x.y.z.9) 56(84) bytes of data.


This happens with Firefox too which is the most annoying for me because
I drop to my personal web server every time the domain is not found. I'd
prefer to see an error instead.

It looks like search option in resolver is enabled somewhere or for some
apps.

192.168.1.1 is my router with NAT and DNS. I only found this dns issue
only on Fedora boxes so far.
