You need a DNS query with a special syntax ( with the IP of blog.hlawatsch.org and the dnsblacklist of heise.de [¹] as example) :
the IP: 217.10.14.27
the query
host 27.14.10.217.ix.dnsbl.manitu.net

your server is blacklisted if the returned answer contains localhost.
youre server isn’t blacklisted if the returned answer is empty.
