I am Running Apache, Cucipop, ISC > DHCP 3, Bind 8 etc Install a second NIC in the new box. give one of your five official IPs to it. Should be nice enough as fallback if your first box goes down. You may host some other services there, too. Spreads the load between both boxes. Setup DNS on the second box as caching server only, feeding off both your primary box and your upstream provider. This way, DNS for in-house services will be available when your primary goes down. If you prefer to slave it's bind to your primary name server, just add the necessary lines to your named.boot.
