All entries in a zone file have to end in the name of the zone.  Since this
zone is named 128.129.93.63.in-addr.arpa, all entries have to be
<something>.128.129.93.63.in-addr.arpa.  129.129.93.63.in-addr.arpa doesn't
follow that pattern, it should be 129.128.129.93.63.in-addr.arpa.

The simplest way to ensure this is to leave the suffix off entirely,
i.e. just write:

129 IN PTR flowpoint.sysintegrators.com.
130 IN PTR si.sysintegrators.com.
....

Names that don't end in a "." automatically have the zone name appended.
