ummm ... Actually RFC 1918 address ranges are a /8. /12 and 
/16 set of ranges.  http://www.isi.edu/in-notes/rfc1918.txt

3. Private Address Space

   The Internet Assigned Numbers Authority (IANA) has reserved the
   following three blocks of the IP address space for private 
internets:

     10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)
------------------

A more direct solution is to widen the defaults.

and an RFE:

On this topic, I was working through the wrappers on a k12 
2.0.2-1 unit, and really think a set of stanza lines this are 
needed:

[herrold server4 html]$ cat /etc/hosts.allow ; cat \
	/etc/hosts.deny
#
# hosts.allow   This file describes the names of the hosts which are
#               allowed to use the local INET services, as decided
#               by the '/usr/sbin/tcpd' server.
