can this be done with wildcards?

[Veaceslav Revutchi]

Hi,

I am looking for a wildcard solution to the following scenario:

1.1.1.1.mydomain.com      A   	111.111.111.111
1.1.1.2.mydomain.com      A     111.111.111.111 

... skiping around 10K records

9.9.9.8.mydomain.com      A     111.111.111.111
9.9.9.9.mydomain.com      A   	111.111.111.111

In other words I need to be able to say something 
like the following in my zone file:
 
[0-9].[0-9].[0-9].[0-9].mydomain.com    A    111.111.111.111

or better yet:

*.[0-9].[0-9].[0-9].[0-9].mydomain.com    A    111.111.111.111

The reason a simple *.mydomain.com doesn't work for me is
because I don't want domain names like 2.2.mydomain.com or
1.2.3.mydomain.com to be resolved. 
To rephrase my question can some kind of regular expressions be
used in named zone files?

Thanks in advance for any advice.
