Need a DHCP app with Reservations for a OSX server (10.2.8)

I need a app (shareware or commercial) that will provide DHCP and run
under OSX server (10.2.8)

It need to have the ability to hand out certain predefined IP numbers
based on the MAC address of the client requesting a number.

I assume the built-in apple one doesn't do this, but i could be wrong.

thanx in advnce,

you might merely need to change the /etc/dhcpd.conf file to include something like
-=-=-=- from dhcpd.conf of isc-dhcp3-server -=-=-=-
# Fixed IP addresses can also be specified for hosts.   These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP.   Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.
host fantasia {
  hardware ethernet 08:00:07:26:c0:a5;
  fixed-address fantasia.fugue.com;
}
-=-=-=-=-

Another option is to change your DHCP range and assign the IPs outside
the range. (Although that is recommended anyway).

Do I need to add all these lines for each entry?

By all these, I mean:
host fantasia {
  hardware ethernet 08:00:07:26:c0:a5;
  fixed-address fantasia.fugue.com;
}


So would it look like....
host larry {
  hardware ethernet 08:00:07:26:c0:a5;
  fixed-address larry.fugue.com;
}
host curly{
  hardware ethernet 06:00:07:26:c0:a5;
  fixed-address curly.fugue.com;
}
host mo{
  hardware ethernet 07:00:07:26:c0:a5;
  fixed-address mo.fugue.com;
}

and so on.

Is that right?

It would also be nice to have a sharewaare app that does it with less
work on my end. :)

I am unfamiliar with the front end for OSX Server's DHCP. I am
familiar with reservations with Windows 2000 Server. Although
point-and-click, the method is still tedious.

I know someone else has a reason to assign lots of static IPs via a
DHCP server, but it's usually one at a time...

I don't even know if you have a /etc/dhcp.conf, although if I recall
correctly, the latest version of MAC OS runs on BSD, so it's likely.

You could use a mail merge in Open Office or Word to make the config file.
Create the appropriate fields in a table/spreadsheet:
hostname MACaddress IPAddress

Mail Merge to:
host <<hostame>> {
    hardware ethernet <<macaddress>>
    fixed-address <<IPAddress>>
}

<<next record>>
...
(Don't copy and paste. the above is an example. Word creates special
characters that look like << and >> if you insert merge field).

Copy and append the result to your dhcp.conf. You may have to restart
the DHCP service.

No guarantees. See if the documentation for your DHCP server is
comparable (man dhcpd or man dhcpd.conf)

As I understand it, the answer to your question is "Yes", you need all
those lines for each fixed IP.

For further clarification, I said above "don't copy/paste", but I
meant, don't copy/paste from *here*. You'll want to copy/paste your
Word Merge fields for the quantity of fixed IP's.

Might I suggest merely giving unlimited expiration to your dynamic
IP's? DHCP is *generally* monogomous about assigning the same IP to
the same MAC address.
