One does not apply masks to zone files. If you want to control the reverse
namespace for a /29, then you need to either:

a) have your provider delegate each address in that range as a separate
zone to your nameserver(s)

or

b) have your provider create an alias for each address in that range,
pointing to PTR's in a zone you control (read RFC 2317 to get a general
idea of how this is done).

Note that in either case the co-operation of your provider is required. So
you might start off by talking to them and finding out what they are
willing to do to facilitate the process.
