Dear Sir/Madam,
I am the ISC DHCP server user. How can I guarantee the
reserved ip that can be assigned to the specified host
anytime even the reserved ip is inside the dynamical
range?
For example,
=========================================
subnet 10.0.1.0 netmask 255.255.255.0 {
default-lease-time 28800;
max-lease-time 28800;
option subnet-mask 255.255.255.0;
option broadcast-address 10.0.1.255;
option routers 10.0.1.1;
option domain-name-servers 10.0.1.1;
option domain-name "";
option netbios-node-type 8;
option netbios-name-servers 10.0.1.1;
range 10.0.1.10 10.0.1.20;
host test {
hardware ethernet 00:12:3F:1F:2C:31;
fixed-address 10.0.1.10;
}
}
=========================================
The fixed-address (10.0.1.10) is reserved for host
"test" and it is also inside the dynamic range
(10.0.1.10 - 10.0.1.20). In this case (I need this
case), the ip 10.0.1.10 could be assigned to a host
"somebodyelse" before the host "test" come to request
a ip.
Plese help me! How can I guarantee the reserved ip
that will not be assigned to "somebodyelse"?
Thanks!
TT
