Here is a link which describes how this feature of IOS works

I am not positive though that it will be applicable in your case.
Best regards,

I do have a static translation for the WWW server and the DNS servers are
translating to the NATed global address. Can you give me an example of how
it is possible to change the DNS reply payload?

Yes, the IOS NAT can change the DNS reply payload, and change the global IP
to local IP, but only when static NAT is configured on Router.
Also there is a keyword that you can use to turn off the feature starting
IOS 12.3 or 12.2T

Subject: DNS and NAT
Is there a solution within IOS to intercept DNS resolution? My issue is
that I have hosts and a WWW server on the same segment. All are being
NATed. The DNS servers sits outside of the Network/NAT and tells the rest
of the enterprise the way to get to the WWW server use this global IP which
has a static translation to the WWW server. The issue is that when the
local host do a DNS lookup they are getting the global IP rather than the
local IP.
I know the PIX can do this with the dns and alias keywords but I am looking
for an IOS solution.
Thanks,
Nir
