Vista and local DNS ?

Im using a laptop with Vista (Business) and IIS 7 for development

associating multiple hosts with the same (local 127.0.0.01) IP address

Currently I edit the hosts file manually to perform the equivalent of a

wildcard DNS entry

As far as I know the local HOSTS file does not support the inclusion of a

single record DNS wildcard A record

So I have to specify every host individually (and there are a lot). It

quite time consuming double checking these against my IIS host headers

Is there an alternative approach that can be installed on the same machine

which will allow me to simple define a single wildcard A record which points

to 127.0.0.1

I understand that there are third party DNS products that might be

appropriate ?

Recommendations?
