Why are they asking for both the DNS server and the IP?

[Jackrabbit Slim]

So if my dsl provider (Pacbell) has assigned me a host name of
"adsl-123-456-789-123.dsl.snfc21.pacbell.net" should I put that into the
first field?

or should I put www.mydomain.com in there assuming that the ip address I put
into the second field will make it stick?

Could I leave the first field blank and still expect it to work?

you want to do it the second way...

first DNS: should be the host and domain name of the box.. aka
www.mydomain.com
first IP: the ip address of the dns server
