dns

my client has around 300,000 domains and they just have a wildcard for all of them

* A   12.12.12.12

Now they want to create a sub domain that points to a different IP and still have the flexibility of wildcard, something like

ww1.*    A   24.24.24.24


*        A   12.12.12.12

Looks like in BIND, the lower "*" is catch-all and taking over every query and hence ww1 is not working.

One of solutions offered by IT folks was to create seperate 300K zones for just "ww1" and leave the "*" wildcard.

Are there any other DNS software's that can achieve this task easily?

Any other ways to deal?
