[vox-tech] procmail question: filtering ranges of IP's

[Peter Jay Salzman]

i got spam today at one of my ucd accounts.  here's the relevent header:

   Received: from server2000 (adsl-nk-A1051.hitron.net [210.201.178.35])
   by landau.ucdavis.edu

doing a whois on 210.201.178.35:

   inetnum:     210.201.132.232 - 210.210.132.239
   netname:     GREATCBF-HT-AP
   descr:       Great Chinese Bills Finance Corporation
   descr:       F11, No.111, Ming-Sheng Rd., Kaohsiung City, Taiwan, R.O.C.
   country:     TW
   changed:     adm@ht.net.tw 20010820
   source:      APNIC

frankly i'd be happy to filter/spamcop any email coming from the range
of IP's 210.201.132.232 to 210.210.132.239.

question:

with procmail, how does one reliably match an IP address in the headers
which belongs to this range of IP's?
