Hello Ron:
I much appreciate your efforts to help! Thank you.

Are you planning on running a separate (private) network for your
cobbler
installs? or just going to use one subnet with DHCP offered from cobbler
with TFTP?
Can't answer this question as I am not understanding what each option
means in practical terms.
I have (so far) four blocks of IPs, in different subnets ... all
servers in one rack only. Not sure what makes most sense for me. But
again, my objective/need is: (a) most important, *remotely*
re-installing Linux OS (mostly CentOS versions) to servers in my
rack, and (b) installing Linux OS on new servers that get added to
the rack.
The "dhcpd.conf" file is on my Fedora 8 VPS Cobbler server at:
/etc/dhcpd.conf
"pxelinux.0" is at:
/tftpboot/pxelinux.0
(and I see there is another one at:
/usr/lib/syslinux/pxelinux.0 )
The netmask in in this case actually "255.255.255.192".
With the below SAMPLE IP (fake IP) 212.44.88.10, if that would be my
Cobbler server IP, would then the below "dhcpd.conf" configured okay?
Specific questions:
"option domain-name-servers" --> Would I add all the IP rangers I
have? Separated with comma? For example:
212.44.88.1 212.44.88.63, 212.48.77.1 212.48.77.255;
"option domain-name-servers" --> Can this be an IP that works for all
servers?

If the settings above are correct -- or after they are corrected,
what is the next step?
Hope all these questions do not bother you too much.
Best wishes,
