i would like to create bash script to discover whether certain IP is listed in some of the blacklist

Here is example service that checks many blacklists http://www.dnsbl.info/
I would know how to use curl to fetch webpage and extract needed data, but there appears be no direct URL to the results of certain IP, i need to submit form (an IP) in order to obtain data with little delay.

How can i using linux commands fetch that page?
