fixed-address problem

No problem. Typos are the root of all evil.

Ah, since you called out the subnet, I looked at the subnet. Not the host address where the error appears to be. My apologies.

Your subnet clause is

subnet 192.168.99.0 netmask 255.255.255.0 {

Your fixed address is

fixed-address 192.168.98.101;

You can't service a subnet out side of the subnet in your declaration

I don't see a problem with the subnet. OP just isn't using the entire pool, right?

I'm not sure what the effect of the "group" declaration is. I believe on my configurations where I'm assigning a static address, I'm just using a "host" declaration. I don't declare these hosts within the subnet declaration, either. I would be inclined to try the host declaration outside the subnet first.

Your subnet is wrong

Hello everyonw,

I am unable to assign fixed IP addresses to host.

I have the following configuration:

option domain-name "cts.org<http://cts.org>";
option domain-name-servers ns1.cts.org<http://ns1.cts.org>;

default-lease-time 300;
max-lease-time 1500;


subnet 192.168.99.0 netmask 255.255.255.0 {

#  range 192.168.99.201 192.168.99.250;
    option broadcast-address 192.168.99.255;
    option routers 192.168.99.1;
    option domain-name "cts.org<http://cts.org>";

  group {
    host vault {
      option host-name "vault.cts.org<http://vault.cts.org>";
      hardware ethernet 52:af:12:cf:87:c5;
      fixed-address 192.168.98.101;
    }
  }
}


With "range 192.168.99.201 192.168.99.250;"  the host is assigned the first available IP address. If I disable "range" like in the shown configuration, the log says: "dhcpd: DHCPDISCOVER from 52:af:12:cf:87:c5 via eth1: network 192.168.99.0/24<http://192.168.99.0/24>: no free leases".

This ISC DHCP 4.2.5.

What am I doing wrong?

Thanks,
Bernard
