Thanks to all who responded so far!  I had a look at some of the 
ports I am using and so far all I found was

  find . -name "*.c" | xargs grep inet_network
./apache13-modssl/work/apache_1.3.33/src/modules/proxy/proxy_util.c: 
if (host[i] == '\0' && (ap_inet_addr(host) == -1 || inet_network(host) == -1))
