isc-dhcp-server not replying to relayed requests

us flag

DHCP request is being relayed from a server in a different subnet to the ISC-DHCP box. ISC-DHCP is not responding

dhcpd.conf is like this:

subnet 10.0.1.10 netmask 255.255.255.254 {} 

host test {
  hardware ethernet 32:b8:ee:57:1e:e0;
  fixed-address 192.168.200.222;
  option routers 192.168.200.1;
  option subnet-mask 255.255.255.0;
}

DHCP request is arriving at this server from 10.0.1.11 but no response. I see this in the logs:

DHCPDISCOVER from 32:b8:ee:57:1e:e0 via 10.0.1.11: network 10.0.1.10/31: no free leases

Any thoughts? There is nothing in the leases file for any of these subnets

So we're understanding, you're expecting host with MAC address `32:b8:ee:57:1e:e0` to be assigned the only available IP address in that subnet, 10.01.11, even though something is already using that address and your DHCP server is communicating with it?

no, host with mac `32:b8:ee:57:1e:e0` should be assigned 192.168.200.222. 10.0.1.10/31 just needs to exist in the config file as that is the subnet DHCP is being relayed from

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
