I'm running into some sort of odd issue: After booting a client, I'm
able to resolve its IP from another client with no trouble. But if I
wait overnight, the next day I can't resolve its IP anymore. It still
looks correct in /var/lib/misc/dnsmasq.leases, so I'm not sure what's
going on.

Connection to 192.168.1.1 closed.
master ~ # host node01
node01.cluster.local has address 192.168.1.1

Any ideas would be greatly appreciated.

Thanks,
Donnie
