[Dnsmasq-discuss] Disappearing hosts from local DNS resolution

[Eric Thibodeau]

Hello,

    I am using dnsmasq as a core component of my cluster. I'm having a 
weird problem where the nodes are disappearing (can't use hostnames 
anymore). So I am forced to connect to them using the IP addr. and 
forcing dhcpcd to request an IP for the hosts to reappear in dnsmasq. 
The logs show the following on the disappeared hosts:

Oct  1 15:29:41 headless dnsmasq[7726]: DHCPREQUEST(eth1) 10.0.1.11 
00:01:03:df:ca:44
Oct  1 15:29:41 headless dnsmasq[7726]: DHCPNAK(eth1) 10.0.1.11 
00:01:03:df:ca:44 lease not found
...

00:01:03:df:ca:44
Oct  1 15:29:42 headless dnsmasq[7726]: DHCPDISCOVER(eth2) 00:01:03:df:ca:44
Oct  1 15:29:42 headless dnsmasq[7726]: DHCPOFFER(eth2) 10.0.1.11 
00:01:03:df:ca:44
Oct  1 15:29:42 headless dnsmasq[7726]: DHCPREQUEST(eth1) 10.0.1.11 
00:01:03:df:ca:44
Oct  1 15:29:42 headless dnsmasq[7726]: DHCPACK(eth1) 10.0.1.11 
00:01:03:df:ca:44 thinkbig1

   Here are two significant lines from my config file:

dhcp-range=AthlonXP_1,10.0.1.10,10.0.1.126,255.255.255.0,12h

dhcp-host=00:01:03:df:ca:44,net:AthlonXP_1,thinkbig1,10.0.1.11

As you can note, I am defining a range with a lease time of 12h but none 
for the statically defined hosts. Could this be the reason the nodes 
disappear (lease time not sent to nodes if it's not defined in the 
static definition)?

dnsmasq version is 2.45 and dhcpcd is 4.0.1-rc1
