4.16.1.2 Address Scope
Scope is a range of IP-addresses within which a server can assign addresses to its
clients. Scopes are located in a configuration database of a server and are
identified by names configured by server administrator when this scope was
created. Scope is created by the following command:
Syntax:
dhcpd add scope <SCOPE_NAME> <INTERFACE|*> <START_IP>
<END_IP>
here
 SCOPE_NAME - scope name. It is not case-sensitive and must be unique. If
scope name contains spaces, server will automatically substitute them with
"underscore" sign (_).
 INTERFACE - name of network interface with which this scope will be attached
(allowed interface). If * is specified as interference, that means that this scope
can be attached to all suitable network interfaces. Suitable network interface
is an interface which contains a subnet of IP-addresses (aliases) that includes
starting and ending IP-addresses of the scope.
 START_IP and END_IP - starting and ending IP-addresses of the scope
correspondingly. When attaching to network interface, it is checked if a range
of this scope does not intersect (and is not included) within another scope that
might be attached to this interface. When IP-addresses are assigned to clients,
only those scopes can be used which are connected to the same network
interface as a client.
In any case, if a scope cannot be attached, it is not deleted.
Add dscope command creates temporary (for 1 dhcpd session) range of
IP-addresses that are not shown in the configuration output.
Example:
#2> dhcpd add scope MSOFT eth0 192.168.177.20 192.168.177.22
[eth0] <192.168.177.12> (MSOFT):
192.168.177.20-192.168.177.22 Scope attached
