DNS hidding

[HuMPie]

Hi,

DNS does only domain name resolving to ip and visa versa
The only and very easy thing to do is to add an additional hostheader in
IIS for that domain so that site will listen on 2 hostheaders.

Hello

I am not a DNS expert but I am sure my problem can be easily solved.

In our office, we use an internal DNS.  This internal DNS implements,
for a given "xyz.com" project, 3 entries:

* www.dev.xyz.com --> points to the private adress of the development
site;

* www.xyz.com --> points to the public production site

* www.prod.xyz.com --> is an alias of www.xyz.com;

www.prod.xyz.com is only used to create some coherence in our work:
when a programmer wants to access a site, he always used the same
convention:

www.[prod|dev].project_domain

The problem is the following:

We use IIS as our production server and since we have a restricted
pool of ip adresses, we had to map more than one project per IP (using
the header split mechanism)

Now when I am in the office and I type "www.prod.xyz.com", the browser
doesnt change "www.prod.xyz.com" to "www.xyz.com" ... consequently, I
am not able to load the public site (since, in prod, no header is
defined for the "www.prod.xyz.com" format)

This problem would not happen if the DNS could "replace" www.xyz.com
when I type "www.prod.xyz.com" ... but I think that a DNS alias only
return an IP without changing the name associated to that IP.

So is it possible to configure my DNS so that when a user ask for
"www.prod.xyz.com", it will redirect to "www.xyz.com" ?

Thanks in advance
