You do not need to tell the Cobalt which IPs are assigned to it.

you first of all set the IP address for the server itself using the 
front panel. If you wish nso.myserver.com to be the name of your 
primary DNS server and your DNS server has IP 192.56.56.56, do the 
following:

1. tell your domain provider that nso.myserver.com is the DNS server 
name you have and has IP address 192.56.56.56.
2.Also tell them that the dns servers for  myserver.com are 
nso.myserver.com and nso.myispsserver.com (assuming your ISP is doing 
the secondary DNS)
3. Set the following DNS records in your raq 3:

Type	Host	Domain		parameter 1	Parameter2
A	nso	myserver.com	192.56.56.56
NS	-	192.56.56.56	nso.myispsserver.com

Once you have done this, dns requests for other Domains which are 
listed as using ns0. myserver.com, will be directed at your server. 
You do not need to assign a specific IP to the DNS serving part of 
the machine. It is important to have your dns server name and IP 
address listed with your naming authority. Otherwise they will be 
going in circles:

Where is www.myserver.com?
Don't know, lets look it up. It uses nso.myserver.com as dns
Where is ns0.myserver.com?
Don't know, lets look it up. It uses nso.myserver.com as dns
Where is ns0.myserver.com?
Don't know, lets look it up. It uses nso.myserver.com as dns
Where is ns0.myserver.com?
Don't know, lets look it up. It uses nso.myserver.com as dns
...eventual melt down!

If your domain name authority has a listing for nso.myserver.com as 
192.56.56.56, then the following will occur:

Where is www.myserver.com?
Don't know, lets look it up. It uses nso.myserver.com as dns
Where is ns0.myserver.com?
192.56.56.56
Where is www.myserver.com?
192.56.56.100 (for example)

I hope this is a reasonable explanation.

Regards,

Jason
