Suppose there's just one Ubuntu / ISC-DHCP (v3) server on the network. I've successfully been able to provide "DHCP reservations" meaning MAC foo gets ip 1.2.3.4, whereas everyone else just gets an address from a pool, etc.
But is it possible to only make the address specific to a particular reservation but also other options like the router and DNS servers?
Example: I want computers 1, 2, and 3 to get addresses from the 192.168.100.10 to 192.168.100.20 range, use 192.168.100.1 as the router, and use 192.168.100.2 and 192.168.100.3 as the DNS servers.
But I want computer 4 to get a particular address (let's say 192.168.100.21), use 192.168.100.4 as the router, and use 192.168.100.5 as the DNS server.
This is my attempt, but I don't think it's right:
subnet 10.100.0.0 netmask 255.255.0.0 {
option domain-name-servers 1.2.3.4;
option domain-name "foo";
option routers 5.6.7.8;
option broadcast-address 10.100.255.255;
default-lease-time 600;
max-lease-time 7200;
host windows-matt-2 {
hardware ethernet 00:1f:d0:a1:55:5d;
fixed-address 10.100.101.21;
}
}
subnet 10.100.0.0 netmask 255.255.0.0 {
range 10.100.201.1 10.100.201.254;
option domain-name-servers 10.100.1.1;
option domain-name "lundfam.local";
option routers 10.100.1.1;
option broadcast-address 10.100.255.255;
default-lease-time 600;
max-lease-time 7200;
}
