External name servers

[hnaparst]

This seems like such a simple question, I'm surprised
I can't find the answer.

Can I use external nameservers instead of running
BIND? Why don't I just tell all my customers to register
a domain name and point their nameservers to my ISPConfig
machine.

In that case, what do I do for the settings in DNSManager.
The manual is quite silent on what all those blanks really do!
Server: Server1 (what's that?)
Domain (SOA) (ehh?)
IP address (of what?)
Nameserver1 and 2 (which would do what, exactly?)
or the New Master and New Slave buttons. What do those
do?

Anyway, I'm just hoping that I can use my afraid.org nameservers and avoid all these unexplained blanks
in ISP config. All I need is for the client's GET request to
come into my Apache server, and I can take care of the
rest.

You dont have to use the nameserver in ISPConfig.

Just dont create DNS records in the ISPCOnfig DNS-Manager, thats all
