SQLIPPOOL/IPPOOL prefix/range format

Hi, SQLIPPOOL requires, maintenance of an IP address table carrying individual IPs Is there a way to handle IP prefixes (prefix/range format) so that in large networks having many different networks could main and utilze this effectively. For example it would be cumbersome if it happens to populate a table with each IP of 10.10.0.0/16. The other query is how would it affect the performance if it happens to scan through the entire table during new ip assignment of a client(e.g. mobile device). On the contrary, Perl has Net::IP for handling ip prefixes which may be better in performance when it comes to large deployments. What is your opinion please ? Is there a way/module to handle this? Thanks a lot for your thoughts/assistance. rg
