I agree.  It looks like you're pointing your clients to use 10.0.0.1 for 
DNS resolution, which I'm guessing is the IP address of your GNU/Linux 
router.  If this is true, then is this router also running a DNS server 
(e. g. BIND or djbdns)?  If not, then you will either need to stand up a 
DNS server and reflect that in your dhcpd.conf, or you can simply use 
the DNS server(s) that your ISP gave you.  I have one internally (my 
K12LTSP server, which I'm using to type this email), so that's what I use.
