Why isc-dhcpd is giving reserved ip?

Question

FreeBSD

The server on freebsd issues ip.
piece of code:

subnet 192.168.100.0 netmask 255.255.255.0 {
  range 192.168.100.50 192.168.100.200;
  option routers 192.168.100.1;
}
host bsd<------><------>{ hardware ethernet 00:13:20:ca:17:12; fixed-address 192.168.100.164; option host-name "bsd";}

The bsd server, which is at 164, has statics manually registered in etc/rc.conf, not via dhcp.
Recently, user machines have begun to receive this address 192.168.100.164.
What could be the problem?

Answer 1

This is not a reserved address.
If a request comes from a poppy 00:13:20:ca:17:12, then it will be given ip 192.168.100.164. In cases where this IP has not yet been issued, then it can be issued to anyone. To reserve an address, you need to exclude it from the pool.
