hacer mediante reservas, pq eso reserva esa dirección por mac, y yo no
quiero reservarlas, solo "sacar" las direcciones indicadas del rango.
Muchas gracias

Puedes crear exclusiones en lugar de reservas. Justamente las reservas van
por mac ya que son direcciones que se "reservan" a maquinas especificas
mientras que una exclusion es la opcion necesaria para que cierta/s IPs no
sean asignadas.

"
Exclusion Ranges When you create a new scope, addresses of existing
statically configured computers should be immediately excluded from the
range. By using exclusion ranges, an administrator can exclude IP address
ranges within a scope so those addresses are not offered to clients.

Because Windows 2000 Server requires that a computer running the DHCP
service have its IP address statically configured, be sure that the server
computer has its IP address either outside of, or excluded from, the range
of the scope.

Excluded IP addresses can be active on your network, but only by manually
configuring these addresses at computers that do not use DHCP to obtain an
address. Exclusion ranges should be used for computers or devices that must
have a static IP address, such as printer servers, firewalls, or routers.

Reservations An administrator can reserve IP addresses for permanent lease
assignment to specified computers or devices on the network. Reservations
ensure that a specified hardware device on a subnet can always use the same
IP address. Reservations should be made for DHCP-enabled devices that must
always have the same IP address on your network, such as print servers,
firewalls, or routers. For more information, see "Managing Reservations"
later in this chapter."





De la ayuda de Windows 2000:



a.. Setting exclusion ranges
You should set exclusion ranges for any IP addresses within the scope that
you do not want the DHCP server to offer or use for DHCP assignment. For
example, you can exclude the first 10 addresses in the previous example
scope by creating an exclusion for 192.168.0.1 to 192.168.0.10.

By setting an exclusion for these addresses, you specify that DHCP clients
are never offered these addresses when they request leased configuration
from the server. Excluded IP addresses can be active on your network, but
only by manually configuring these addresses at hosts that do not use DHCP
to obtain an address.

exclusion range An exclusion range is a limited sequence of IP
addresses within a scope, excluded from DHCP service offerings. Exclusion
ranges assure that any addresses in these ranges are not offered by the
server to DHCP clients on your network.



COMO HACERLO:
==
To exclude an address from a scope

1.. Open DHCP.
2.. In the console tree, click Address Pool.
Where?

a.. DHCP
b.. Applicable DHCP server
c.. Applicable superscope (if used)
d.. Applicable scope
e.. Address Pool
3.. On the Action menu, click New Exclusion Range.
4.. In the Add Exclusion dialog box, type the Start IP address that
you want to exclude from this scope.
To exclude a range of more than one IP address, type an End IP
address.

5.. Click Add.
Notes

a.. To open DHCP, click Start, point to Programs, point to
Administrative Tools, and then click DHCP.
b.. Addresses that are excluded from the scope are not offered by
the DHCP server to clients obtaining leases from this scope.
c.. You cannot exclude a range of addresses that includes an active
lease. You must first delete the active lease and then retry the exclusion.


Saludos!
