npf.conf tables | blocks of addresses

[Darrel <levitch%iglou.com@localhost>]

Hello,

I want for my hash file table to contain address blocks; e.g., 127.0.0.0/8

It seems that when anything other than a single address is in the table 
then this error is thrown:

 (hostname nor servname provided, or not known) near <tableFile>

Is there some alternate way of dealing with address blocks in npf?
