For simplicity's sake I'd like to keep even IPs for servers themselves (or for the use of the server's primary function), and the following odd ones for their RACs
Assuming we get /28, we have 14 IPs at our disposal.
+Trogdor, +Novastorm, +Tiamat, +Bahamut, +the new hosting server and +Sirkain are our hardware.
For exampe, using the typical 192.168.1.x net:
70.33.186.196 Trogdor
70.33.186.197 Trogdor RAC
70.33.186.198 Tiamat
70.33.186.199 [reserved] Tiamat RAC
70.33.186.200 Bahamut
70.33.186.201 [reserved] Bahamut RAC
70.33.186.202 Novastorm primary
70.33.186.203 Novastorm RAC
70.33.186.204 [reserved] Hosting server primary
70.33.186.205 [reserved] Hosting server RAC

70.33.186.221 | Trogdor second IP for facdn.net
------------------------------------
70.33.186.222 | Sirkain
All servers have 2 NICs.
One of them should be plugged into the colo's switch, the other to our 1Gbps LAN hub. Sirkain server stays separated from our LAN.
Thus all servers should have both the 1Gbps LAN and the shared 100Mbps WAN connectivity.
I do not know how would we need to go around about assigning these IPs to our servers, but I imagine it will be something like:
Dragoneer and net-cat bring in the servers, install them and plug them in. Then net-cat is given a keyboard and a monitor to locally log in and assign the IPs/netmasks/gateways/dns servers to the interfaces.
Check that the links are up and accessible from the outside.
Case-by-case basis:
* RACs on Nova and Trogdor can be assigned an IP address from the BIOS, as far as I remember.
* Trogdor: local login and change, or postpone and do it later over the virtual KVM from within the RAC
* Tiamat: local login
* Bahamut: doesn't have an external IP. Either local login and assign, or postpone and do it later over LAN.
* Novastorm: Virtual KVM from within RAC.
* Sirkain: I do not know how it has been handled between Sirkain and Dragoneer.
