i asked a question before about bind and the capabilities of being able to redirect to a search page if it is unable to locate the real domain...
I been looking into it and have come across wild cards?
is this what i would need to do this.
I am currently running a small isp and would like to redirect all non existing domains to a portal  page but am unable to locate the documentation for doing so.
anyone have any ideas?
thanks

Does your server act as a public resolver (do your clients use it to resolve non-local public names)? Or does it just answer for a fixed set of authoritative domains?

If it acts as a public resolver using a Wildcard really won't help. You would have to claim responsibility for "." and add the wildcard there. You would not be able to get answers from other servers in that instance.

the server acts as a public resolver for our clients that are currently on dial up..

Create a new zone called ".", a root zone.

But if you do that you won't be able to resolve any public name unless you have a zone for it. That is, you won't be able to resolve www.google.com without a zone for google on this DNS server. It won't do what you want here if the server is being used to resolve public names I'm afraid.

Different DNS server software probably. You're using BIND?

I can't speak of the detail, I've never worked for them but if you've seen them do it then I won't doubt it happens.

I know SimpleDNS can do it, I know MS DNS cannot, and that BIND has little documentation that I can find on it.

I believe OpenDNS did it at some point, not sure if they still do. I know Verizon did for a while, much to everyone's utter disgust :)
