DNS changes

[Guest]

Need some assistance on configuring a new external DNS.

I have to retire our old box and Microsoft recommonds I do not swap the IP
and host names due to an exchange migration. I have a Windows 2000 network
environment with internal DNS running. I will be installing DNS - external on
other box to communicate to the outside world.

I have read a lot of white paper on the dns creation (split and namespace)
that I think I am just getting more confused: I have a question about
creating the zone on this box (external) My internal domain name is e.g.,
rrrrr.sssss.bbbbbb and the registered domain is kkkkkk.com. Do I just create
a new zone - with the registered name on the outside world and create all the
records within that zone? also - do I create an alias or CName --- if I want
to have the HOST known to the outside world different than the what the host
name is?

Need some assistance on configuring a new external DNS.

I have to retire our old box and Microsoft recommonds I
do not swap the IP and host names due to an exchange
migration. I have a Windows 2000 network environment with
internal DNS running. I will be installing DNS - external
on other box to communicate to the outside world.

I have read a lot of white paper on the dns creation
(split and namespace) that I think I am just getting more

You would create a zone for the public domain under two conditions.
1. You host sites and or services locally AND you are behind an NAT device.
Because you are behind NAT those sites and services are only accessible
locally by their private IP. So you need records for your local machines to
use to connect to those site by name.
2. You are hosting the Public zone for any domain, whether your or someone
else's.

If both 1. and 2. are true, you need two DNS servers one for public records
and one for private records.

also - do I create an alias or

CName --- if I want to have the HOST known to the outside
world different than the what the host name is?

Yes and maybe, some records cannot use CNAME records, one is mail server
host names that are used in MX records the other is NS records. These
records must have "A" (Address) records for glue.
