Hi Frank,
I'll put some comments inline...

The netmask in in this case actually "255.255.255.192".
so that means a maximum of 63 addresses available.
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?
This is a list of IP addresses that the dhcp clients will configure as
DNS servers (ie should end up as 'nameserver a.b.c.d' entries in
/etc/resolv.conf)

I think you mean subnet 212.44.88.0 netmask 255.255.255.192 {
option routers 212.44.88.10;
ok, your cobbler box is the router, or gateway to the rest of the network
option subnet-mask 255.255.255.192;
option domain-name-servers 212.33.44.55;
your dns server for the dhcp clients will be at 212.33.44.55
option domain-name "newdomain123.net";
the suffix of your dns domain is
newdomain123.net. This should appear
in the /etc/resolv.conf file as an entry 'search newdomain123.net'
range dynamic-bootp 212.44.88.1 212.44.88.63;
this range will overlap your cobbler server. I'm not certain if the
dhcp daemon is intelligent enough to avoid 212.44.88.10 or if it will
potentially offer it to a client. I would change this to '212.44.88.11
212.44.88.63'.
I would personally consider moving the cobbler server to IP address
212.44.88.1 and make the range '212.44.88.2 212.44.88.63'
filename "/tftpboot/pxelinux.0";
default-lease-time 21600;
max-lease-time 43200;
next-server 212.44.88.10;
the cobbler server is also running the tftp service.
