I have domain and dns server which is registered on the net. This will need an external ip for www usage as it will host a website. I also want to add a mail server for the company, will this require another external ip address or can it somehow use the first external ip address?
One other quick question about DNS - (BIND) - When configuring the reverse lookup sones and you point the ip address' at the name like this:
1.249.249.192.in-addr.arpa. IN PTR host1.domain.com
