You must do this administratively with you registrar so the new the
registered HOST names are updated in your domain's root servers.

The internal configuration is your business. To Internet, when a
resolver asks port 53 of your DNS host's ip "what is the ip for "ns1"
host, your DNS responds: "218.232.198.5".
But, in the special case of DNS hosts, to know the ip address of your
domain's DNS's in the first place, the resolver (DNS client) obtains
the NS's A record ip from the root servers, not from your DNS. That's
why you can't renumber your DNS HOST locally without first and also
modifying the HOST records and thereby the glue A records in the root servers.

The "Advanced" panel is for "alias ip's", ie, the ip's bound to an
interface that are in addition to the "default ip" or "canonical ip"
on the "IP Address" panel.
How you set your ip's up internally, ie, whether you have one or 20
ip's on the machine, is your business. The outside world can't know
and doesn't care as long as DNS queries to an ipaddress:53 find a DNS
service there.
I assume your running NT4 DNS and I don't know how/if you can tell it
to "DNS listen on" a specific ip, but if you're running BIND8 for
Win32, you use the option in the options section of named.conf:
listen-on {ipadress_list;};
