<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri","sans-serif"; color:#1F497D">If you happen to have nagios (or a nagios compatible system) you could use check_rbl to monitor the range on an ongoing basis.</span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.5pt; font-family:"Helvetica","sans-serif"">The quickest way would be just to write a quick script that loops through the dns servers for the RBL's that you want to check against for each IP address

DNS work for you. They also send you email reports daily showing what IPs are blocked etc.</span><span lang="EN-US"></span></p>
