Wildcard DNS script

[MichealC4]

I've seen them before, but the place I saw it appears to have removed the listing, probably because the author didn't maintain it. However, searches have turned up little. I'm thinking about doing wildcard DNS, but of course I need a script to handle it. Anybody seen these? I could write one myself I guess, but I don't particularly have the time to with everything else I need to do.

You don't need a script to do DNS wildcards and they have nothing to do with PHP. What would this script do?

For the DNS wildcard itself, no. I know how to do wildcard DNS. However, what it supposed to handle the requests?

Am I being obtuse? What requests?

Okay. For example:

I'll have a wildcard DNS record in my zone. Then when one of my users requests it, the script will check to see if they have an account and it is authorized to to use the subdomain.

ie: username.myname.com But if username doesn't exist, what will happen? What will happen with any requests in wildcard DNS? It'll just go to my main site.

username1.myname.com
usernameasdasdfasdf.myname.com
asdflkasjdfasdfasdfasdfasdf.myname.com

Those will all point to myname.com unless I do something with them. So what do I need to do?

That's the opposite of wildcards. What you're asking about would have to be handled in your web server configuration. You may be able to write a script that looks at the URI and switches based on the named requested.
