The ISC server does **NOT** automatically fix this configuration error for you - but the above warning was added some years ago to alert people to the issue given that many were being caught out by it.
I tried making the pool smaller in case that was an issue and it
complained about the static reservation not being in a subnet...
relevant excerpt from config:
subnet 1.1.1.0 netmask 255.255.255.0 {
option routers 1.1.1.1;
pool {
range 1.1.1.2 1.1.1.250;
}
}
host StaticCustomer {
hardware ethernet 00:11:22:33:44:55;
fixed-address 1.1.1.200;
}
host DyanmicCustomer {
# keeps stealing address
hardware ethernet 66:66:66:66:66:66;
fixed-address 1.1.1.201;
}
