dns help

[Thotapalli, Ravi (Metamor)]

Hi,

I have a dsl connection at home and its hooked to my linux box. My Isp has
given me two Static IP add and I have a domain registered. Inorder to host
DNS (primary) server do I have to get IP addresses from NIC again ? (this is
for my personal use only) also is it okay if I install DNS server and my
firewall on the same server along with my web contents.

Thanks
ravi
