yes, there is a tool, written by ADM group, available on
http://packetstorm.securify.com/groups/ADM/ADMIDpack/src/

also if you search ddns on packetstorm you'll find a tool
"Distributed DNS Flooder v0.1b by Extirpater"
"A powerful attack against DNS servers. DDNSF will send lots of queries to
disable DNS.
If DNS daemon software logs incorrect queries (like most of do), affect
will be greater."

this does not attempt to fill named's cache, yet to destroy it by
performing tons of (bad) queries.
